GLG sends you to lunch with a few would-be peers, then puts you through a half-day of interviews with various managers/team leads throughout the firm. The questions focus on case studies for above and beyond client service and how you work under pressure.

good company 3 rounds of interview. They had a case study and then i went in person and interviewed with 3 people. everyone there is very young. I felt like the questions were what i expected them to be.
