Overall pretty straightforward, had an HR interview, then an interview with a case study, then a panel interview with a few senior members. As long as you prepare and do the research should be fine.

I met up with 3 people, and all of them tested me in a way. The recruiter approached me for a healthcare position, but I was still quizzed about their general section. I had to do a case study and pitch GLG to a client. I was well prepared, make sure you read everything on their website. However, the feedback I received after the interview was awfully useless.
