I applied online. I interviewed at McKinsey & Company (Gurgaon, Haryana) in May 2025
Interview
The interview process is quite simple: apply on website, hear from HR, hacker rank test - 2 python+2 sql ques, interview with senior manager. This interview was a bit overwhelming for me because the interviewer kept dismissing my opinions about a case study and tried to shape my thoughts into the one structured way. However, I think in case studies, there are no right or wrong answers and should be more open ended.
