I thought this interview was asking about past experiences and questioning why you are here to a not normal extent... I definitely would have liked the conversation to flow better.

I applied via Linkedin and was contacted for a 30 minute phone screening with one of the Investment Managers. After that I moved on to the next round and had another 30 minute phone interview with another manager. The final round was a 4 hour interview consisting of 4 one hour long interviews one of which was an investment case study. All the phone screening and subsequent interviews were behavioral and consisted of questions about my resume and experiences, why I applied and things of that nature.
