Interview Process   |   Interview Puzzles / Aptitude
Organization : McKinsey
Position : Software Developer
I applied through a consultancy firm and the process took more than a month. Since they hire mainly through such firms, they are quite clear on the requirement on the very first note.

First Round: Interview Round

Some questions were asked to check my IQ I guess as they were some reasoning puzzles and were neither easy nor difficult. It's good I had prepared for that. Some technical questions were asked as well.

Second Round: Interview Round

This interview focused more on my past experiences and other questions regarding the projects I have done. Some random questions like 'Why McKinsey?' were asked as well. This was the best round for me.

Third Round: Technical Interview Round

This was the most difficult round. Many technical questions were asked by the interviewee and mostly were based on c++. I was not able to answer all of them correctly. Some more questions about the past experience were asked as well.

Overall experience at McKinsey was really fine. But make sure you prepare your best as they simply want to recruit the best.

Thanks Jackinson for sharing the details of your interview.
