I applied online. The process took 1 day. I interviewed at McKinsey & Company in Oct 2009
Interview
McKinsey invite people with advance degress from premier schools, the interviewing process consist of a DA/DI round followed by 2 case study session which accordin to them are just test processes but I personally believe they evaluate the candidates in this process. The result for the first round of interviews are declared the very next day.
Interview questions [1]
Question 1
The business case was regarding a wine 2 competing wine companies producing 3 class of wines in a given fictitious location. The aim is to achieve a 10% growth rate of one of the company.
Straightforward, well structured & well explained. Long duration, with 5 30-ish minute interviews total spread out over the course of a couple of weeks. Great support, information on requirements/evaluations readily available.
Too long - too many rounds. Had to play a game first, then multiple rounds. No follow ups after I was rejected - I got ghosted.
Did not enjoy it - obviously this was a long while back and I was too young to notice but not a good behaviour. Truly no respect.
The process made me feel very unprepared but I was able to get through with all of my studying. I would recommend anyone about to interview with them look at Harvard Business cases as reference
