2 phone calls, IQ test online (insulting), in person interview. Everyone was nice, but their examples of case studies were pretty lame. If this is how they screen their candidates then I don't know how they stay in business. Some even seemed jealous of my experience.
- Asked why I wanted to be a consultant. Would I move to NYC?

Pretty odd and unprofessional. At first, the interview process started pretty straight forward. It started off with a phone screen and a very easy IQ/attention to detail test. The next round is a one on one case interview via skype which is pretty basic. The final round is a five hour day with two behavioral interviews, three case interviews, and a 15 presentation on a subject of your choice. I went through the phone screen and the IQ tests which were pretty easy. Upon the skype interview though - the interview called me thirty minutes early and offered no explanation. Overall he was kind of weird and made rude and odd faces when I was presenting him with my logic. He was somewhat standoffish. I made it to the final round but the day before my interview C1 canceled it to reschedule. Nobody ever reached out to me to finish up the process and I ended up taking an offer with a different company.

It was very easy-- I had an initial phone interview with general HR questions. Then there was an online exam with very simple math and grammar questions. Finally a skype interview with a small case study involving market sizing and looking at a few graphs. Unfortunately company was sold before the final round of interview

Interview was through campus recruiting. They took about 1 week to send me an email that they were interested, and then we set up a Skype interview. I was fairly excited. However, the interviewer did not turn on their Skype camera, so we essentially just had a poor vocal connection with no image. The interview took about 45 minutes, and was focused on both programming and statistics. The interviewer, although nice, was very hard to understand. The questions were not terribly difficult, but did require some thought. By the end however, the interviewer seemed as if they wanted to get on with their day. They answered my questions with "it depends", and were not descriptive. Based on the other Glassdoor ratings, I'm not shocked. I had the feeling that the position was filled, and that they wasted 45 minutes of my time.
