I applied through an employee referral. The process took 3 months. I interviewed at GLG in Nov 2018
Interview
The interview process was a bit chaotic (I got a phone call out of the blue for a phone interview that I hadn't gotten any details about beforehand), but it was pretty comprehensive. I had the chance to meet a lot of different people in the team I eventually worked for.

Question 1
I was asked standard behavioral questions in most of the interviews, and had a case study/case study review for another round. One question I was asked was if I was willing to work late/weekends, which retrospectively isn't the best standard to be setting. This was a few years ago though, so this might have changed.
Pretty straightforward- 3-4 rounds of interviews, discussing your background and prior job experience or school history to reviewing case studies, to discussing location preferences and salary expectations. Overall easy interview process.
