Typical PEI interview plus case interview. Total of 5-6 rounds of interviews with McKinsey employees of varying levels of seniority. PEI interview is similar to the questions in McKinsey websites whereas case interview is similar to Case Coach, Crafting Cases, and other case prep websites.
I interviewed at McKinsey & Company (Ciudad de Mexico)
Interview
Interview process was really great, all interviewers were friendly and professional. Started with a phone screen, then two case interview rounds with a partner and a senior associate, followed by a final round covering fit and problem-solving skills

Question 1
Tell me about a time you had to influence someone without formal authority
It was a one-to-one interview with a consultant. It's a typical case study. The experience was traumatizing. I know my answers weren't great, the consultant was elegant and didn't bother to hide his boredom.
