IQVIA Asociate Consultant interview questions

Went through campus recruiting through my masters program. first round 2 interviews back to back, case and behavioral. not hard. second round was 4 interviews. Simple written case where I was asked to present 5 slides on my recommendation on portfolio management for a "client". 3 behaviorals otherwise. Not hard HOWEVER, This company did me dirty. They loved me, and they ended up being our client for my next project through my Masters. I saw my interviewers and worked for them on that project, and they wanted to give me an offer, but they said there was no headcount available. they evaluated my case month by month for 4 months, and still can't come up with an offer. All is well as I'm pursuing my MPH now as a backup, but they never had the ability to give me an offer in the first place. They took weeks to reach a decision. Didn't keep appointments to talk about offers, and ignored calls and emails.

I had the following are the interview rounds : 1) Phone screen with Principal - Behavioral 2) Phone Screen with Principal - Behavioral + Technical (Industry Knowledge) 3) On - Site Interview: a) Behavioral with Consultant b) Case interview with Senior Consultant c) Group case study 4) Phone Screen with VP
