McKinsey visited our college campus for the post of junior data analyst ( name of profile offered is confusing ,it's basically software engineer ). Drive consisted of three rounds . 1st was a coding round hosted on hackerrank platform.3 questions were asked ranging from medium to difficult. First two questions were implementation based and third question was based on tree data structure. To clear this round make sure to solve ATLEAST one question completely. From 80 , 9 people were shortlisted for 2nd round. 2nd was pair coding round.In this round each candidate was assigned a mentor whom they had to explain the problem and their approach to solve it before coding.It consisted of 1 question to be solved in 75 mins . After this round 4 people were selected for interview. First was technical interview followed by HR interview on Skype. Finally 2 were recruited.

1 online test, 1 technical, 2 behavioral, 1 Situational, VP round. I had 6 rounds and process went for 2 months. And at last I have not received any feedback from them.
