Applied online but already knew people working at McKinsey and had interacted with recruiters during on-campus events. Note that they screen online applications by university so unless you go to a target school, applying online is useless. First round was 2 interviews in their NYC office with a Business Analyst and an Engagement Manager. Standard case + PEI. After clearing this round, you need to select which office you would like to apply to (I hear that certain ones are harder to get than others based on your profile - NYC and Bay Area are more difficult I think). Second round was 3 interviews at the office you selected. 2 of them were standard case + PEI with Partners at the firm One was a more open conversation with questions about past experience and my resume with a Director. He was trying to sell me on McKinsey 10 minutes into the interview. They were very professional throughout the entire process and really tried to sell me on McKinsey after giving me an offer. They've built a really great recruiting process. Ended up declining the offer to work in another industry because I didn't want to become a management consultant and these kinds of old-age jobs lacked the entrepreneurial environment I was seeking.
