I just had my Bain interview and in one (of two) cases I had to calculate the Revenue of a business. Once I got to the number the interviewer stopped me and questioned my figure. I ran through my numbers and confirmed then but he stated that while my calculations were off, there was something I was missing. I went through the question again and he said that it was from the beginning. I finally realized that in the prompt he stated that 50% of revenue was given to X source. I then got the correct number and he seemed to laugh it off but the process of checking my math took potentially over a minute. Is this viewed as a big negative, or if the case went well otherwise would it not be a dealbreaker?
Ha, just saw this! Right back at you!
