Average interview

Application

I applied online. I interviewed at McKinsey & Company (Copenhagen, Capital Region) in Apr 2026

Interview

Long, but transparent and effective. First two tests were their online assessments, followed by two case interviews, followed by by a partner interview, on presentation and fit. Process was somewhat slow and and bureaucratic though, with a lot of weighting. One interviewer seemed unprepared.
