Considering it was an internship i felt that 5 interviews were a bit of an exaggeration. It took so much of my time as well as the company's time. My first 3 interviews felt really fair. However, on my last one the recruiter was uninterested in me from the start. He was laid back in the chair which was a stance that made me feel he was not focusing on what I was saying at all. In the end my HR recruiter told me I was declined the position by the last person because I was rude and kept interrupting him. Truthfully, i cannot imagine anyone who is being interviewed for their dream job being rude to the person responsible for hiring them.

It was behavioural and case based. Behavioural and case both lasted around 15-20 min each. Behavioural is easy as long as you prepare. I found the case interview difficult-interviewer was not encouraging either.
