GLG interview questions

1st phone call lasted about an hour and focused on resume, behavioral, and a few problem solving questions. Next, the on site was 4 interviews over the course of 5 hours regarding similar points and also a case study. The team was really nice and accommodating. Trip was expensed which is great.

Applied online in February, received an email 2,5 months later and scheduled a phone interview that same week. The interview was pretty standard and went on for about 25 min. I was told the recruiter would get back to me within the following couple of days, however I did not hear back for a month (I did send 2 follow-ups in the meantime). The whole process went on from February until May which I found absolutely unreasonable for a position like this one.
