GRAND PRIZE WINNERS - Mihnea Munteanu and Zachery Jacobson

In a very short time, I went from literally not knowing anything about consulting—coming from an undergrad major that doesn’t often partake in the consulting route—to securing job offers with the two top firms in the industry. Victor helps you obtain a fundamental understanding of what consultants do and the skills needed to succeed. Victor emphasizes structured thinking, structured communication and teamwork—skills that really are tested during the case interview and ones I use on a day-to-day basis at McKinsey.

What Victor does a bit differently from the competition is that he really focuses on unveiling why and how the interviewer is looking for these skills, and then he demonstrates how you can best show these skills on interview day. For example, Victor emphasizes that you really need to communicate your logic out loud during the case. The case interviewers look for this because as consultants we do this every day, and Victor appropriately emphasizes this aspect. After I was hired at McKinsey, I was told I had done really well in this respect in the case interview. Even though I have always communicated my thoughts clearly, if Victor hadn’t highlighted this for me as an important skill, I probably wouldn’t have focused on showcasing it during the case as much.

One aspect that I think really made a difference in securing multiple offers was applying Victor’s advice about how to draw effective conclusions in a case. I had a really tough case in one of my interviews that bounced all over the place, and suddenly I had to tie all the pieces together. Because I had practiced formulating my conclusions in the way Victor suggested, according to the interviewers, I was the only candidate up to that point to conquer that case. Victor’s advice really helped me structure the conclusion in a concise way. I really would recommend Victor’s materials to any candidate going through the interview process. They are consistently very high-quality resources, and they’ve helped me a lot.

When I began preparing for consulting interviews, I realized that my background as a PhD candidate in engineering had left me completely unprepared for the case interview process. So I did my research. I began looking at every piece of case preparation material that I could get my hands on. I bought books, I looked at online materials, studied standard frameworks, looked at consulting club slide decks, you name it. I found that they each had slightly different procedures for how to solve cases, and a lot of them had complicated flowcharts or long lists of questions with advice on what question to ask exactly when. None of them had one thing: None of them taught you how to think.

That’s when I discovered Victor Cheng’s materials, and that’s what makes Victor Cheng’s techniques different. Instead of asking you to memorize 12 different case systems or what question to ask exactly when, it teaches you how to form hypotheses and then test them. Using this hypothesis-driven approach, you’re able to use the information you’re given to ask the right questions that help you find that gold nugget that makes you think, “Hmmm … that’s interesting,” that you can use to crack open the case and solve it.

In my personal interview process, Victor Cheng’s techniques helped immensely. In one case, I was going down a rabbit hole, and I just couldn’t find a solution. Before, I would have been stuck and really not known what to do. But thanks to Victor’s techniques, I was able to go back and look at my previous hypotheses and realize that I had another one that I could test, which ended up being the solution. Overall, Victor’s techniques gave me confidence, and not only do his techniques help in the interview process, but they’re going to help me for years to come as a consultant.

After my interviews, I was given feedback that I’d solved cases that they hadn’t seen anyone solve before, and I usually had ample time to spare. I ended up getting my dream job as an associate at McKinsey & Company in New York, and I have Victor Cheng’s technique to thank.

2nd PRIZE WINNERS - Warren Cheng, Michael Yang, Bernardo Clementino, Daniel Suo, and István Mag

While applying to different consulting firms, I used many different resources—books, interview coaches, alumni connections, various consulting guru blogs … you name it. Having seen and used many of these materials, I can say for sure that Victor Cheng’s material was the most useful in helping secure my offer. And that is for three reasons specifically: his versatile approach, the way he communicates like a consultant and his passion for the subject.

Victor teaches not just frameworks but also a high level of thinking. This way of thinking helped me solve my case interviews regardless of the case type I received, whether it was an M&A, market entry or turnaround. His approach required that I memorize nothing more than a few simple business ideas. Because I was studying in the U.S. while applying to be in an Asian office, my rounds of interviews were with consultants from both the U.S. and Asia. Because of this, the cases I received ranged from straightforward number crunching to brainstorming with partners on subjects spanning both continents. I would have long ago been disqualified if I had stuck to simple framework memorizing. Thanks to Victor’s approach, I was able to adapt to different situations while leveraging logic and my own business sense.

I also learned from Victor how to communicate like a consultant. It is easy to lay out: structure, signpost and synthesize. But to actually do it in a case interview is another matter. In all of Victor’s materials, whether through email, voice recording or video, Victor keeps reinforcing the consultant way of communication. It was so ingrained in me after having gone through his case prep materials that I started talking this way myself. One partner told me after my interview that my summaries during and at the end of the case (what Victor calls “synthesis”) were clear and concise, which is uncommon in associate-level candidates. Even to this day, having been a consultant for a while, I still talk in the same way and am praised for being concise in my communication.

Finally, the most influential part about Victor is his passion for consulting. Victor is not only good at cracking case interviews, but he likes solving them as well. Only with passion can someone dig deep into analyzing the entire interview process: from dynamics in the behavioral portion to techniques and body language to watch out for during the case portion. Victor’s passion for the subject makes the daunting task of prepping for cases a little more fun. And I would argue that this was the key to my getting an offer from BCG—with Victor’s approach, I came to like practicing and actually doing case interviews.

There is no doubt that the road to a consulting offer is a tough battle. And I was really fortunate to have Victor on my side. I could not have gotten my BCG offer without his help.

Thank you, Victor!

I’ve said it before and I’ll say it again: I honestly could not have done any of this without all the resources Victor provided. With the help of LOMS, the hours of free videos on your website and your many invaluable emails/articles, I went from getting only two first-round interviews as a junior to getting 11 first-round interviews as a senior, making it to eight final rounds and securing offers from each of the six final-round interviews that I had at McKinsey, BCG, Booz, Deloitte, A.T. Kearney and Marakon, all in New York. I ended up accepting an offer at McKinsey’s New York office and could not be happier. From what I hear, it’s the first McKinsey New York offer for a Northwestern student in several years.

Everything Victor said was right: Decent grades and a good set of experiences will only get you so far. At the end of the day, it comes down to the case interview. Victor’s free videos were what got me started in terms of case prep, but LOMS took it to another level. Thinking out loud, being hypothesis-driven, structuring the conclusion, addressing risks—these are all tips that any other case interview prep resource could deliver. However, Victor’s materials are the only resource that DEMONSTRATES how to do these things the right way.

After listening to LOMS over and over again on my iPod (it became a daily ritual on the train ride to and from my internship), I absorbed everything that I needed to know about how to behave during a case interview. In particular, LOMS was crucial in helping me get as many offers as I did, especially the second iteration of the car wash case. By showing exactly what constituted a borderline case performance, Victor highlighted for me the key things that I had to do to take me over the top. In the two weeks before my final rounds, I practiced those two or three key things over and over again until they became second nature by the time I walked into the interview room. Essentially, by wading through the many complexities and nuances of the case interview process, Victor freed me up to actually operate at my best in terms of analysis, problem solving and cracking the case.

Beyond just case prep, Victor’s articles about consulting-ready résumés were also critical to my success. I followed his advice about getting a brand-name internship during the school year in addition to having great work experiences during the summer. That spring internship actually ended up being the main catalyst not only for my résumé but also for meeting numerous ex-consultants who introduced me to their former colleagues. It also enabled me to develop meaningful project experiences that would serve as my main stories during McKinsey’s final-round personal experience interview and other behavioral interviews.

Victor, I can’t thank you enough for all the help that you have given to me and the rest of this community.

I started to write this message to deeply thank Victor Cheng for all the guidance he provided me during my interview process for the big consulting houses over the past year, but in the end it looks more like one of the many success stories that he gets from people like me. In my case, by the end of a long and winding process, I managed to secure an offer to work for Boston Consulting Group in the Helsinki office— which I have heard is one of the best offices to work at in the world!

To ideally express how much Victor’s work has influenced my life and career, we need to go back a bit in time.

A couple of years ago I graduated as an industrial engineer from one of the best universities of my home country, Brazil. Back then, I managed to reach the end of the recruitment process with a top consulting company but failed miserably during the interviews—the last stage after six other phases of the process. Despite being aware of the case interview concept, I had no clue how deep the topic could go.

The truth is that I was not fully aware of what was being asked of me and, more important, what would be the best way to showcase my abilities through the case interview format.

Several months later, I moved to Finland for personal reasons and started a master’s program in strategy at Aalto University (the school from which about 90 percent of Finland’s MBB hires come from), without losing my motivation to enter consulting.

At school, I was introduced to Caseinterview.com by a colleague, and from that moment, I would dedicate some time almost every day to learning about case interviews. The more I read, the more fascinated I became with the topic and the more I understood how complex and deep case interviews can be— and how well they can be used to evaluate a candidate.

Through this process, I became extremely impressed with how easy Victor makes case interviews seem! When listening to Victor interviewing someone, the structure of the case, the words chosen and the way to pose an initial hypothesis looked so obvious and easy that, at that point, it made me extremely frustrated while trying to practice with a partner. I honestly sucked!

But it was also from Victor and his frequent emails that I gathered motivation to continue practicing, understanding that with this type of interview, practice DOES make perfect! And here is WHY Victor Cheng was the perfect coach: He went beyond the nuances of the case interview itself to provide us, the members of his community, with great insights on how to write our cover letter and CV and land the interview. He would even sometimes prompt me, through his messages, to consider whether consulting is really for me—I am glad to say that it is indeed!

From all his material, videos, blog and LOMS program, I learned three great life lessons from Victor Cheng:

1. Network. Make yourself known to the companies! In my opinion (and Victor’s as well), this is the best way to land an interview. In my case, being a foreigner, it was very tough, but I didn’t give up easily. I ended up creating the first consulting club in Finland. No wonder that MBBs were very interested in getting to know the 100 students who joined the consulting club of the best university in the country.

2. Practice (and practice, and practice!). Victor taught me to look at case interviews as I would a game—the more you practice, the better you become. Simple equation. From my personal experience I have learned that practicing with a peer produces the best result. This way, apart from simulating the reality of an interview scenario, you also have the chance to interview your colleague and see how easily you can spot mistakes while sitting on the other side of the table!

3. Don’t Give Up. Once you are sure that consulting is your thing, grab it with both hands. I did not give up after my first attempt a couple of years back. I was for sure motivated by my will and also by the several success cases that Victor shared with us about people who, just like me, had failed before succeeding.

In my case, after networking, practicing for almost a year and not giving up, the interviews seemed more like leisure time!

Interestingly, here in the Nordic countries, BCG does not give feedback in between rounds of interviews. They argue that once the candidates were told to, for instance, smile more or be more relaxed during the next interview, they would actually behave in an extreme way in order to compensate for what was done in the previous interview. This would often cost them the offer. When I was invited to sign the offer, I took my chances and asked for some sort of final compilation of comments on the whole process. The chief of staff was brief and said that these things are usually confidential, so not much could be revealed. One thing he said he could share was that the interviewers unanimously agreed that my case-solving skills were indeed outstanding.

And that is how Victor Cheng helped me get my dream job. Thank you, Victor.

I was a recent Harvard undergraduate. During school, I became fascinated by the great ideas in business and psychology and their growing intersection—what makes certain people or institutions successful and others not? While the focus of management consulting was then (and is still) less about psychology, I really believed that I would find the experience incredibly invigorating and could even someday help lead new revolutions in business thinking (e.g., MIX). Full steam ahead.

Attempt #1—Failure (Drowning in Information)

In school, I was a top performer and excellent presenter. I also had significant experience effectively leading large groups of people. And if there was ever an ocean to be boiled, I vaporized it, going through every possible nugget of information on case interviews (including Victor’s Case Interview Secrets, which were the most helpful), practicing more than anyone else I knew. However, I failed every one of my interviews with McKinsey, Bain, BCG, Oliver Wyman, Monitor, Booz and probably a few others.

Under the stress of an actual interview, I took nuclear weapons to deal with anthills and completely overthought each question. I prepared in the most naïve way—the way I had always prepared for things and exactly as Victor suggested not to—and was sorely disappointed in myself. Looking back, though, at least my consistency was remarkable.

Attempt #2—Success (Case Interview Secrets + LOMS = K.I.S.S.)

It wasn’t until nearly a year and a half later (and well into my then-current job) that I stumbled onto Victor’s Look Over My Shoulder program (LOMS). I wasn’t planning to interview again, but after a few minutes, I knew LOMS could get me the offer. Before, I had the best tools (Case Interview Secrets) and enormous amounts of material (all my reading and thoughts), but I was missing the instruction manual. I immediately downloaded LOMS to my phone and listened to it nearly 24/7. By the time I submitted my résumé to McKinsey a few weeks later, the entire interview process seemed like a formality—I was that good. What happened?

1. Victor showed me what the interviewers were looking for.

With LOMS, Victor had done all the testing for me—what works and what doesn’t. From applying Victor’s advice about structuring ideas down to adopting specific speech patterns, I learned to sound and think like I had already been working at McKinsey and that the interview was just another problem-solving session.

2. Victor gave me the chance to practice obsessively.

I’m a big believer in “practice makes perfect.” With Victor’s materials, I was able to practice in the right way as much as I wanted. Before, I didn’t have anyone (even among many friends) who wanted to practice as much as I did and certainly didn’t have someone who could provide crucial, on-point feedback.

3. Victor gave me confidence (now this sounds like a bad song …).

This is more a corollary of points 1 and 2 because guided practice builds confidence, but it was the deciding factor in my ultimate success.

The PARADE Method

The PARADE method rounds out Victor’s prep materials wonderfully. With his help, I was able to give such good responses to personal experience questions that my interviewers were actually speechless on several occasions. I prepared for the personal experience interview in three steps:

1. I prepared a PARADE summary for the three or four question archetypes for four experiences (around a dozen summaries). These are what I gave as the initial response to personal experience questions.

2. I broke down each of the four experiences into 15–20 discrete actions or scenes and answered the following questions:

a. What was I thinking?

b. What were others thinking?

c. What did I say, and why?

d. How did others react?

3. I practiced giving my PARADE summaries in the mirror while filming myself (probably one of the more awkward things I’ve done).

Positive Externalities

Since digesting Victor’s case interview materials (alone, never mind the “How to Succeed in Management Consulting” stuff), I have also become a more effective presenter and a more effective thinker. While I won’t be starting at McKinsey for a few more months, my work at my current employer, Goldman Sachs, has improved so much that senior people are taking notice. In fact, I was recently invited to meet with the former CEO of Goldman Sachs International, and he specifically followed up afterward to begin a potentially lifelong relationship. These unexpected benefits make me re-realize how deep the advice Victor gives actually goes … . I can’t wait for more good surprises!

I’m a 23-year-old business student and future first-year associate at Boston Consulting Group. I think BCG extended me an offer for a lot of reasons—one of them being the fact that I spent at least 50 hours reading and applying Victor Cheng’s advice and watching his videos.

When I got the invitation for the interviews with BCG, I felt ready for the challenge because of my academic and professional background. However, I postponed the interviews until after I’d completed my summer internship at an M&A boutique in London. I came to see the wisdom in that decision when I started reading Victor’s emails while doing my summer internship and realized I was so far from being prepared.

Of course, I had asked my friends about their interview experiences and knew I would have to prepare well for the interviews, especially because BCG was my dream workplace, but also because I wouldn’t have thought I had basically no knowledge of how to do well in these very special interviews.

After realizing I lacked the necessary knowledge, I dug deeper into the topic and repeatedly went through Victor Cheng’s lessons. Victor taught me how to prepare both methodologically and mentally, and this is what sets him apart from the competitors.

As for his methodological approach, I found it extremely useful that Victor not only described basically every minute of the interview but also explained how you should start and then drive the interview, how you can ensure that you don’t miss points of utmost importance, and how to draw a conclusion that’s based on a thorough and structured analysis at the end of the interview.

As for mental preparation, Victor’s guidance was crucial for helping me better understand the interviewers’ mindset. I also managed to lower my stress level by accepting Victor’s comforting reassurance that after extensive practice, even if you don’t do well on a case interview, it doesn’t mean you’re not talented; it only means consulting is not for you, but you can be equally successful in other fields of business and life.

Because I think I managed to follow most of Victor’s advice, I got good feedback after my interviews. Although these were my first consulting interviews and I had the chance to do only two mock interviews beforehand, I was told afterward that I seemed to know what I was doing and seemed confident, and my thinking process was well-structured.

Although I had been indirectly training for consulting interviews for years, without Victor Cheng’s guidance, I probably wouldn’t have received the offer from BCG.

Thank you, Victor Cheng!

I have been following Victor Cheng's Case Interview lessons for almost three years now. Over this period, I have become quite a Business Analyst and landed a dream Internship as a 3rd year undergrad. If it wasn't for Victor Cheng's coaching, I would have been trying to reach a destination without a road map. Victor's approach is very tactful when solving business problems and his frameworks are very effective and help you organize your thought process. Also, his style of teaching is quite motivational as he understands human psychology that drives successes and failures in life. His lessons are not just about solving business problems but they have also been life lessons for me. Thank you Mr. Cheng, Thank you for everything!

My name is Cosmin Leonte and I currently not working in management consulting but that is my goal. I work for Unilever Netherlands.

Through your materials I have learned more than reading any books or guides. Yes, I might not be working in consulting yet, but I practice and apply your tips and hints everyday, not to mention the skills that are required in the industry.

I gather and I make notes on most of the things you say and people started noticing. I have more structure in my approaches at my current work place and friends told me I should be working in the industry. The way you structure your ideas and present techniques are things that I take away.

Victor teaches a partner or high ranked way of thinking. Thanks to Victor I am able to structure and infer ideas that are not common at people at my age and rank.

Victor tells you to act and present like a consultant. Though my work is a little different from a consultant’s, I receive praises for being concise in my communication both verbal and written.

What I learned from Victor the most is that you have to like what you do, and I like doing this. I am challenged by having mock interviews and by the possibility of joining the industry.

I have made so much progress without discussing with you so I can only think that the opportunity to be your trainee would only propel my development.

Thank you very much!

Cosmin Leonte


I have been checking and analyzing Victor´s videos, emails, and website for about 4 years, and since then I can tell you that my skills to master the business case interviews have improved significantly, along with Victor´s new additional coaching services offer on his webpage.

Caseinterview.com and Victor not only help you on how to follow the structure and procedures to pass the most important job interviews at the elite consulting firms, but also and most important, how to overcome the feelings of failling and the lonelineess of being rejected along the road.

In addition to these motivating feedbacks and coaching benefits, Victor also suggest that the most important tools to succeed in the challenging consulting world are: PEOPLE´S SKILLS and "THE BLUE COLLAR SKILL" (which means know how to sell your service)

Thanks to Victor and Caseinterview.com I have gotten to grasp the essentials on how to prepare well on the consulting world, as well as understanding better my guidelines in managing my professional career as a top executive in the future.

Even though I have not gotten in the top three firms by far, I was able to get into a business strategy department of an international renting car franchise in Ecuador, as a Corporate Account Manager. In this departament I have learned and been able to apply some business case interview scenarios in real life such as entering a new local market with the franchise brand, increase the market share with new services, and analyze why profit,sales and cost have increased, along with getting new corporate clients.

I know that I am still far away to achieve excellence to be considered a highly skilled consultant, but if the consulting world was not mean to be for me, at least I have the advantage and pleasure to apply the consulting tips such as: sinthesized method, the formulation of hypotheses and extrapolate information.

Believe me these tips, allow me to think outside the box, and avoid the rutinary management operation skills, that that means a lot.

As I was looking to transition from banking into consulting, my past experience and network helped me secure interviews with most of the big consulting firms. But as I discovered after my first interview with Oliver Wyman, this was clearly not enough to get an offer.

I tried many of the books and training options for case study available online, went through pages of GMAT exercises and asked consultant friends to give me mock case interviews. Everything made sense, I felt comfortable and yet I still just got to the final round of McKinsey. I was good, but something was missing.

And then I discovered Caseinterview.com and LOMS. It was a complete breakthrough. Listening to the cases for hours on end, replaying the great pyramid principles, the mistakes and Victor’s corrections just cleared my mind and organized my thoughts. For one month I spent about five to six hours a day listening to LOMS while continuing some of the side training and reviewing Victor’s case interview secrets. The frameworks and case analytics eventually just became a part of who I was, and I could hear Victor’s advice in my head as I solved new cases. From then on, I went on nailing every case interview I got.

I have been an incredibly happy senior consultant at Monitor in London for the past six months, and I owe much of this happiness and success to Victor’s LOMS training. His advice and tools unlocked my potential and gave me a consultant mindset. Thank you.

It took me about a year to achieve my goal of getting into a top management consulting firm. Looking back, I realize that not only did I succeed in the interview process, but I also changed substantially during that time. Victor certainly made an impact on my life. I see him as one of my mentors. Two key things I learned from Victor:

1. I learned how to ace consulting interviews. Victor and the material he creates are by far the best sources on consulting interviews that exist. I was given feedback three times in between the interviews, and each time the interviewers thought I was really strong and had no suggestions for improvement. This kind of feedback helped keep my confidence high so that I continued to perform well.

2. I learned how to use structured analytical thinking beyond case interviews. My decision-making process has improved a lot. I now constantly build and review my personal strategy that includes important facets of life: family, social life, health, spirituality, professional development. I believe that this approach will lead me to great success and satisfaction.

None of it happened, of course, without hard work. Combine Victor’s advice with actions on your part and you will notice the changes, and it will build up over time to create a significant shift in how you see things, how you act upon them and what you finally get.

With the help of Victor’s guidance, among other things, I was able to secure and accept an offer from BCG. I stumbled across Victor after my first-round interview with BCG in Canada. I had used the various guides to make my way through the first round, and after receiving feedback, I needed more structure for the next round. Victor’s character and dedication to seeing others succeed contributes significantly to his students’ successes— and also makes cases much easier to analyze.

Victor’s methodology was not so much to memorize multiple frameworks but to memorize one thing: to segment the problem at hand! When in doubt, segment! I will always remember that, because it applies to every single business issue in the world—that’s where the root of analysis comes from. Victor is able to engage with his students, especially me, because I continue to keep up with the newsletters and emails he sends out.

Coming from a small-town, non-top-tier business school and ending up at a top three consulting firm in the big city (and now consulting for the United Nations), I highly recommend Victor to anyone looking to first get into, and then succeed in, the management consulting world.

Without all of Victor’s help through the LOMS program, I would never have been able to secure an offer from BCG. The LOMS program improved my ability to look at the problem in a structured way and to find the solution in the best way possible, which really differentiated me from other candidates. All of Victor’s tips are what make the difference between those who get offers and those who don’t.

After passing McKinsey’s PST, I went to a case coaching lesson and was among the 20 percent who hadn’t practiced a case interview yet. That is when I found out about Victor’s page and resources. It definitely helped me get started in case interviews, and I took those practice materials everywhere I went.

Victor’s materials gave me a clear understanding of how to structure a case interview with a highly logical approach, which was always valued in the interviews I had. This helped me get offers from BCG and a boutique firm and get to McKinsey’s last round (which I declined because BCG was my top choice).

After using Victor’s materials, I had a better idea of what the consulting world looked like, and with practice and perseverance I received the offer I wanted.

Thanks, Victor!

I would like to THANK you for the help you provided to me in my recruiting process and beyond that but also to TESTIFY that your material really helps in various fields. The acknowledgment part is important since it provides the key points of WHAT I have learned through your material and personality. Then, the testimonial actually shows HOW it has worked for me.


There are 3 dimensions that were impacted during my preparation. I identified them and I would like to acknowledge EACH of these.

As a PhD student in chemistry, I was not familiar at all with the overall approach of a case interview as opposed to other candidates (i.e. with MBA background) that are usually aware of the general process. This gave me the opportunity to be the most COMPLETE TARGET (receptor) among the customers segments [;-)] of your teaching since I took benefits from EACH 3 LAYERS of the learning process that you shared with us via your different materials.

Firstly, you FAMILIARIZED me with the CONCEPT of a case interview. Initially, you introduced me to case interview BASICS and MINDSET. Then, your FRAMEWORKS helped me to get more SENSE of how to match the RIGHT problem solving approach (structure) to the case. You showed me the relevancy of being both QUALITATIVE and QUANTITATIVE. – Thank you for that!

The second part was the INTERNALIZATION via learning on a deeper level. In this respect, your method (i.e. LOMS and daily e-mails) helped me to be ACTIVE in the learning process. This is very relevant, since it enabled me to be conscious of the HABITS that I needed to incorporate but also it helped me to BUILD those habits in order to develop a CONSISTENCY in my THINKING (structure analysis) and COMMUNICATION skills (phrasing). – Thank you for that!

Finally, you helped me to make the DIFFERENCE with other candidates. The automatism mechanisms that I developed following your method allowed me to devote my brain to CREATIVITY and CRITICAL THINKING (out of the box), and my body to ENERGY and STRESS CONTROL during the interview. These values are extremely significant during the case interview. The nuances of your INSIGHTFUL comments forged me these particular ABILITIES that participate clearly to INTELLIGENCE development and improvement. – Thank you for that!

Victor, the 3-step process I just described is drastically important. Indeed, all together it conveyed a PERLOCUTIONARY act mainly on 2 levels.

CASE-SITUATION adaptation: Through your teaching material, I developed very specific skills. I have learned WHY and HOW being HYPOTHESIS-DRIVEN. This ability is the main driver that really CONDUCTS all type of case analysis. The hypothesis is the starting point of the THINKING and the DATA-DRIVEN approach shapes that THINKING. Moreover, if I know WHEN to apply and HOW to adapt the STRUCTURE and the PHRASING, then each specific situation can be aced. You helped me to understand this and apply this for my case interviews. – Thank you for that!

LIFE-SITUATION adaptation: I do think that this specific METHODOLOGY applies in REAL LIFE as well. You conveyed to me your RATIONALE and the ANALOGY with HOW to solve daily issues with a third party, organize my argumentation, and communicate it became obvious. – Thank you for that!

The last level of impact of your programs is strongly linked with PSYCHOLOGY. And there are 2 additional life lessons I took from you.

Your personality and web-site policy (i.e. refund policy) contribute to the learning as well. One can learn from your FAIRNESS and HONESTY. You deliver a message but you deliver it in a RIGHT and NICE way. This favors the TRANSMISSION but also can be taken as a MORAL lesson. – Thank you for that!

The last point I would like to mention is about your advices to OVERCOME rejection or pressure. This is important because you prepare people to the REALITY and how to MANAGE the EMOTIONS. This can be taken as life lesson as well! – Thank you for that!


I am here to factually SUPPORT that what you teach actually WORKS.

It works on the CASE-LEVEL because I am getting on a FINAL ROUND at Mc Kinsey in Switzerland. The feedback of my interviewers – I had 3 interviews – were: “We liked your CREATIVITY and ENERGY”. It meant to me that I was developing that DIFFERENCE interviewers look for (third dimension). After familiarization and internalization, I was just enough stressed to convey my CREATIVITY and ENERGY to the interviewer.

It works on a more GENERAL-LEVEL daily with my colleagues at work – I am still working for my thesis. I am applying the CONCEPTS I have learned with you to DEVELOP my research and ANALYZE my results. It impacted discussions with friends as well. In fact, the QUALITY of discussions I have around politic, science, or economy improved with your orientations upon PRACTISING of your method.

After all, the interview process is a function of 2 variables: the CANDIDATE and the INTERVIEWER. We can meet all kind of interviewers. Your life lessons really HELPED to be at ease with everyone.

Thank you for EVERYTHING.

I firmly believe that Victor Cheng’s materials are the best source of information for learning what consulting firms are looking for during interviews and how to apply those skills in a time-efficient manner. I began preparing for consulting interviews about a month before what ended up being my final-round interview. I was very frustrated initially because other popular guides such as Case in Point and the Vault consulting guide made it very difficult to practice cases without a partner. It wasn’t until I found Victor Cheng’s materials that I was able to refine my skills enough to land a summer associate offer with BCG Canada.

Over two very intense weeks, I was able to use all of Victor’s materials as a crash course in consulting, which was even more important for me coming from an engineering background. The materials Victor presents really emphasize the importance of hypothesis development over frameworks, which was a key factor in my interview success. In addition, Victor not only states what to do in an interview but also tells you why you should do it. Knowing the logic and reasoning behind what consulting companies were looking for made it much easier to answer both fit and case questions in a way that demonstrated my consulting strengths. Finally, Victor’s materials are extremely good for learning how to “ace the case” by yourself. The simplicity with which he presents his materials makes it easy to absorb the information, even if you do not have access to live practice.

Overall, I would say that Victor’s materials played a major role in helping me secure a summer position at BCG, and I would recommend his materials to others, especially those who are going through the case interview process alone.

Victor Cheng’s was the most useful case prep material I used to prepare for my McKinsey interviews. Victor is effective because he focuses on behaviors and habits that make you successful and not just on frameworks. Unless you have access to McKinsey consultants who can coach you one-on-one, your best bet is Victor Cheng!
