Application

I applied through college or university. I interviewed at L.E.K. Consulting.

Interview

Two rounds of interviews. First round is two 30min interviews, with the first 10min small talk & fit, 20min of case interview, so pace yourself well in the case part as it's a lot shorter than other case interviews. Second round is three more interviews with managers and partners, consisting of two regular cases and one written.

    Interview

    First round: (a) Market Sizing, (b) Case
    Second round: (a) Market Sizing, (b) Case, (c) Brain Teaser with Partner

    This was the most well executed, thorough, and professional recruitment experience of my life. L.E.K. has proven itself to be among the elite consulting firms, up there with the Big 3, regardless of relative notoriety.

    Easy Interview

    Application

    I applied through college or university. The process took 1+ week. I interviewed at L.E.K. Consulting (San Francisco, CA) in January 2017.

    Interview

    First round was 2x 30 minute interviews with Consultant/Manager level staff. First was a traditional case, though accelerated, seemed to focus on math. Second was a more informaal, conversational/idea-generation case. Very quick! After pleasantries, we had only 20 min for cases.

    Second round was: 1 hr for written case (given 30 slides, boil down to 7 slides to make presentation), then 30 minutes to go over case (20 min to present, 10 minutes of Q&A). Then 2 additional 30-min interviews with partners, which were "walk me through resume" and then a short case involving idea-generation & math.

    Difficult Interview

    Application

    I applied through college or university. The process took 1 day. I interviewed at L.E.K. Consulting (Los Angeles, CA) in November 2016.

    Interview

    Two back to back on campus interviews that lasted an hour each. The first interview was a case where the interviewer just wanted to know what type of questions you would ask in order to solve it. The second interview was a market sizing question. Each interviewer only asked one behavioral question before the case. My second interviewer had really analyzed my resume before hand and had highlighted certain parts and wrote certain questions on it that he had for me.

    Application

    I applied through an employee referral. The process took 1 day. I interviewed at L.E.K. Consulting (Los Angeles, CA) in December 2015.

    Interview

    First round consisted of two 30-minute interviews. First interview, with a partner, consisted of behavioral questions and a basic market sizing case. Second interview, with an engagement manager, consisted of a more in-depth problem. Interviewers were professional, but friendly. Unfortunately, as this was a phone interview, my connection kept dropping (something that usually never happens for me), which invariably had an impact.

    Application

    I applied online. I interviewed at L.E.K. Consulting (Los Angeles, CA) in November 2014.

    Interview

    I had back-to-back phone interviews with two consultants, each being 30 min long. I was provided brief profiles of my interviewers, who were friendly on the phone. With just a few minutes of small chat, we went straight into the case. One was a market sizing case and another was a typical profitability case, both were fairly easy to solve.

    Interview Questions

    • One was a market sizing case where you had to state your assumptions and the interviewer will also provide you with some numbers that you can do your calculations with. I'm afraid I can't remember the details of the other case.   Answer Question

    L.E.K. wants to see you've done your research into the firm and the "Why L.E.K." question should be compelling and not generic.

    Application

    I applied through college or university. The process took 2 days. I interviewed at L.E.K. Consulting (Boston, MA) in March 2010.

    Interview

    Received an interview invite through on-campus resume drop. I was one of 12 MBA students interview on the day. It was pretty standard affair. A couple resume-based questions, and then straight to the case. The case was a marketing sizing question. I didn't handle that well at the beginning, but straighten up at the end. The interviewer was a consultant in the PE field. A very nice guy. I got the rejection a day after. Two of my classmates went on to teh second round at Boston office.
