Long interview process since I was applying as a off-cycle hire. Consisted of an initial phone call with the recruiter, followed by round 2 case interview with 2 entry level employees, followed by a round 3 case interview with 3 senior level employees. The first round is relatively basic market sizing and market entry questions with basic algebra. Final round is more quantitative, however, one of the three interviews is more discussion oriented with no math involoved.

Presentation
Interview
I applied to LEK in November 2022 during the regular summer internship app cycle and got invited to interview January 3, 2023. The interview consisted of three parts; first is a workplanning activity that simulates day-to-day activities that are part of the job and where you are supposed to justify how you choose to manage your associates, second is a presentation where you are given a deck of slides and asked to design an executive summary of your recommendations in 1 slide and then present for 10 minutes. After is a Q&A on your presentation. Last part is the case interview. Overall the interviewers were respectful and seemed eager to chat. Had a consultant and a partner reach out after the offer was made to chat more about the firm and office culture and other things.
Interview Questions
Some questions on the workplanning activity were difficult to answer due to ambiguity. For example, how would you adjust the workload for Associate A if it turns out that he has a history of burnout?
