I just wanted to say thanks for providing your case interview video so generously online. I've donated $47 on your behalf to Kid Power.
I'm a physician with no business background and using pretty much just your videos (also read a bit of Marc Cosentino's book but didn't really have like-minded people to practice cases with), I've just received an offer to start as an Associate at McKinsey. Thanks!
Congrats! The first person who put my materials to use and got an offer was an MD who also got an offer from McKinsey a few years ago. He got a photocopy of a photocopy of the original workshop I did for a few friends several years ago.
And it was this first MD's success that inspired the idea that maybe I should share this information more broadly. So I'm glad it worked out for you.
