    Application

    I applied online. I interviewed at L.E.K. Consulting (Los Angeles, CA) in October 2013.

    Interview

    A few weeks after I apply online, the recruiter reached me by email. Then is the 2 back-to-back case interview on phone, one from SF, and one from LA. The cases are quite easy, one qualitative market entry and one quantatitive market-sizing. I got excellent feedback from the interviewer but never heard back from them again. I wrote to recruiter and finally after 2 weeks I got rejection letters. Quite depressing. Anyway, the interviewers are quite welcoming and friendly.

    Interview

    Basic consulting interview. Tell me about yourself followed by case study. Two back to back interviews. First case was very open ended. Did not seem like there was a specific answer the interviewer was looking for. Second case was total opposite. Very detailed with lots of data. Interviewer tried to lead me in a specific direction.

    Difficult Interview

    Application

    I applied through an employee referral. The process took 5 weeks. I interviewed at L.E.K. Consulting (Chicago, IL) in September 2015.

    Interview

    Far and beyond the most professional firm I interacted with. The whole process from beginning to end was done impeccably.

    I come from a midwestern non-target school and got my interview accidentally. I connected with a former VP, who enjoyed our conversation and subsequently my resume and passed it on to a current VP, who then connected me with the Managing Recruiter.

    A few months later, I had a phone call with an Associate and then a Senior Associate in a back-to-back 30-minute interview (general questions with market sizing, then case interview). I heard back within 2 hours that I was invited to their Chicago office for the final round in 2-3 weeks.

    L.E.K. paid for all travel (airfare, taxis, hotel, etc.) and was very courteous in checking up prior to the interview to ensure that all affairs had been taken care of.

    The final round interview was 3, back-to-back-to-back interviews (market sizing, then strategy case, then brain teaser, with questions about my resume mixed in to all of them) with a Manager, Senior Manager, and then the Managing Director. There were 3 candidates at the time and we rotated between the L.E.K. staff, so the order is by no means guaranteed.

    Final round was on Friday and I heard Monday that I did not get the position. Nonetheless, I respect L.E.K. more than any firm for their professionalism and the manner in which they conducted themselves. I strongly recommend everyone consider seriously working there. Great firm, great people, and great career trajectory.

    Application

    I applied through an employee referral. The process took 2 days. I interviewed at L.E.K. Consulting (Boston, MA) in June 2007.

    Interview

    Employee referral led to in-office visit, although I had to contact the HR person a few times first. Interviewed with 2 consultants, both PhDs in life science. 45 mins each, behavioral and cases, with the cases coming from actual projects they had worked on. LEK emphasizes quantitative analysis and the cases probe on that, but they were not too difficult. Behavioral part focuses on why LEK and how you'll fit. 2nd round was the following week with 1 manager and 2 partners. All were behavioral and cases, with more emphasis on fit. Overall, the interviewers were sharp and friendly. The work culture was focused and hard-working, everybody is pretty busy during the working day.

    I applied through college or university. The process took 1 day. I interviewed at L.E.K. Consulting in October 2009.

    Interview

    The on-campus interview included two different interviews. Both had cases and generally they spent 10 or 15 minutes on behavioral and the rest of the time on cases. One case was very quantitative, the other was very much grounded in strategy and didn't really involve numbers. Everyone seemed really nice and willing to help!

    Difficult Interview

    Application

    The process took 1 day. I interviewed at L.E.K. Consulting (Los Angeles, CA) in October 2007.

    Interview

    Initial communications made at the career fair and "consulting night" on campus. After that, it consisted of applying for the position through the on-campus website. After being selected, there were two case interviews for the first round, which was held on-campus. These are each 30 minutes long, with each containing about a 15-20 minute case interview, one is more quant (market sizing), the other is more strategy focused. After that, there was a similar set of interviews during the 2nd round, located at the LEK office in Los Angeles. Here, there are 4 interviews, at least 2 cases, and 1-2 "fit" interviews, typically with engagement managers and VPs (partners)

    Interview Questions

    • What specific moment or event or experience in your life gave you the clarity that consulting is what you're bound to do?   Answer Question

    Negotiation

    Very little room to negotiate. L.E.K. and consulting firms in general all have very comparable offers for the Consultant position. I was, however, able to negotiate my start date, and it seemed as though there was ~flexibility up to 3 months in either direction
