GLG interview questions

Standard CV screening. First interview was with an HR and lasted about 15 min. Second interview was a case study - value chain task plus a role play, lasted for 1h 30min with 3 different Associates. Last round was a 2 hours interview at their EMEA headquarters, with the vice president, head of department and the head of Reasearch.

Application online followed by a telephone interview which lasted about 20 minutes. When I got the call for the interview they informed me the job I had applied for had been taken but only after we'd be talking for about 10-15 minutes... They said they'd consider me for another role but never heard back even though they said they'd call before the end of the week. Interview questions were underprepared and didn't really get much out of it.
