First i had a phone interview which lasted about 15 minutes with questions regarding the company and why i applied to that specific internship. They answered the next day and they invited me for an interview at the headquarters. The manager was very nice and open and he showed interest in knowing me better. He went through the CV and asked some general questions about why i applied for that internship and about my technical skills. Although i didn't get the job the experience was very nice.

On campus interview, I interviewed with who would end up being my manager. Very conversational, I did a lot of talking. They were very interested in whether I would be a good fit for the culture more than the technical experience I had in Finance at the time (as I didn't have any). Lots of behavioral based questions but nothing too tricky or intimidating.
