2 first round on-campus - behavioral questions first followed by case interviews. Leadership experience, challenging situation, persuading someone. Be sure to have good stories and be ready to share the details when being pressed further. Cases were tough, required a lot of mental math. Always speak out the logic and don't hesitate to ask for a minute if it helps you give better and more logical responses. 3 final round interviews in office - with two partners and one senior director. Great learning and humbling experience. Cases were a good chance to showcase your thinking process. Once you get to this stage, it means you have beat a lot of highly qualified candidates and you have solid skills. Enjoy the final rounds. Stay humble, be coachable.

I spent several weeks networking with many people at McKinsey, getting to know the culture, the work-life balance, project placement, etc before I even submitted my application. After I received the interview invitation, I spent several additional weeks running cases with some of the people I had previously met, which helped me feel much more comfortable about the interview process. During the first round of interviews, they had me meet with 2 different people. One was a former associate and one was a current engagement manager. Each interview consisted of an indepth discussion about 1 job related experience I have had. They then went into a case, which had me develop strategies for the companies presented.
