Tech M&A Intern

Hirevue with a few basic behavioral questions
I received an email immediately after inviting me to a 1 on 1 interview with an associated. It was meant to be 30 mins but ran much longer and was grilled pretty hard on technicals.
I was then invited to a Superday about a week later with a director and an analyst. I was given a case study that again ran over the time frame and was grilled pretty hard on technicals.
After the superday, I had another 1 on 1 with one of the group heads and chatted with him for about an hour. Very friendly and enjoyable conversation where he told me about his experience in the group and we discussed my interest.
