GLG Research Associate Professional Service Teams interview questions

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.
