Case Interview Articles

Question about a Written Case Interview: I have made the second round interview at a consulting firm. I was expecting to have a case interview face-to-face, however I have been advised in this round the format will be a written case where I need to prepare a powerpoint presentation from a large amount of reports, [...]

I’m often fond of saying that: Math Never Lies, But It Does Often Mislead Let me give you an example to illustrate this point. Let’s say you use math to analyze a client and discover they generate $100 million in profit. Is this good or bad? It’s a simple question. From a math perspective, all [...]

Question: I’m really hoping you reply to this email if you get the time. I have final round interviews with Roland Berger on Saturday morning. I’ve done a couple of interviews so far and apparently they went well. I watched all your videos and they have been extremely helpful. I have a question though: when [...]

Question: I am a big fan of your materials (LOMS and HSMC are both very helpful). Wanted to ask you a quick question about concluding cases. I think the materials do a great job of covering HOW to close a case. However, what I am struggling with is knowing exactly WHEN to conclude. As I [...]

Do you do it before each new question is asked? After? At [...]

Question: I purchased LOMS about ten days ago and have listened to it twice so far. I am trying to go over the seven times mantra, hopefully before the first round. As far as identifying my weak spots, I feel it’s with the “qualitative” cases, something that you mention is a common issue with people [...]

Question on Using an Issue Tree: First, I would like to thank you very much for your LOMS program. I found it very helpful. Your emails are also very useful for me to learn many new things from other people’s experiences. My questions is about how to structure a case after a case question is [...]

Question: I work in the Venture Capital Industry and am considering a switch to strategy consultancy. Normally people switch the other way around but I think that it would be good to acquire more analytical, team and strategy skills, as I started in the VC field straight from campus. While orienting myself in the strategy [...]
