The day before my interview, I was invited to join the UBS recruitment team for a small dinner at my school. The entire team was very cordial and I had a great time getting to know them all before the interview the following day.
For the interview itself, it was primarily just a run-down of my resume and who I am. No technical questions, and there was sufficient time at the end for me to ask questions as well.
Overall great experience, bummed I didn't get an offer.
