I had a telephone interview, which was a phone screen. And then I was flown in for an in-person interview consisting of 2 rounds of case studies, and a third round if they were still interested after the first two.

I applied online through an internal employee referral. The entire interview process took two weeks. A member of their Career Management Team reached out a few days after I applied for a position through their application portal, and a phone screen was arranged for the following week. The phone screen consisted of mainly behavioral questions, and the person interviewing me probed a couple of items on resume. My second round phone interview was scheduled a few days after the initial phone screen, this time with a member of the team that I was interviewing for. I was asked to do an Excel assessment before the second-round interview, which I did under a set time period the day before the interview itself. The questions that were asked during the second round phone interview were mainly behavioral and skills-based. I was then invited to an third round in-person interview the following week at their DC office; this consisted of two one-hour interviews. The first interview was part behavioral, but mostly a technical/skills-based interview. I was quizzed about my knowledge of data files and data structures via a theoretical scenario. The second interview was with the head of the team that I was interviewing for the position with, and that consisted of behavioral questions followed by a case-style interview. While I am disappointed that I did not receive an offer, the entire interview process was smooth the entire way, and I had a very positive experience every step of the way. The Career Management team was always in touch with me and and were very transparent about where I was in the interviewing process. And most surprisingly, among all interviews I've done with multiple organizations, this was a very expeditious process I've been in from start to finish. I am very impressed by how this was all handled (even if the outcome wasn't what I wanted), and I look forward to future opportunities with them in the near future! P.S. Looking over the reviews of interviews from both successful and unsuccessful applicants here on Glassdoor has helped prepare me for what to expect during the interview process at The Advisory Board Company. This definitely helped me out a lot as it provided me insight to things I might not have expected or thought of in the first place, and I encourage anyone to do the same!
