Microsoft Software Engineer internship interview questions

I interviewed in 2 stages, both technical. First a lighter question at my uni (they were doing a recruitment event) and the second was in a different city. I mentioned that I had to go by plane because it was far from me and they paid for both the plane and the accommodations. The first round was standard, just the technical question and I got asked to rank my interests. On the second round there were 4 sessions with 4 different interviewers. First asked a behavioral question and a tech question, second tech and desing, third two tech questions, fourth only one tech question but I think I was meant to go back and forth more as I got a "if you had asked me I would not have allowed X but I love that you did it" (I think I added some error checking that was not necessary, it was a long time ago)
