I applied online. I interviewed at L.E.K. Consulting
Difficult but managable. My interviewers were very friendly and I really did feel like I got a good sense of the company from it. Their cases were a little ambiguous but other than that I had no complaints.

Anonymous Interview Candidate in New York, NY
I applied through college or university. I interviewed at L.E.K. Consulting (New York, NY) in Sep 2023
First round - two interviews; Final round - three interviews. First round interviewers were very nice and supportive. Final round interviewers composed of higher level employees, such as a manager and a partner. Final round interviewers were disengaged: one of them skipped introductions and even seemed to be dosing off a bit during the interview. Kept nodding without listening even when the answer to my questions/comments was a "yes".

Standard process, 15 mins bq, and 25 mins case 5 QA. You would expect life science cases, instead of other cases. 3-4 behavior questions, 15 mins seem very strict for each interview
