I signed up for the interview during a campus job fair. The first interview involved meeting (virtually) with the recruiter from the job fair, as well as a programmer. The interview was mostly basic interview questions like "why do you want this job" and "tell us a little bit about yourself". The programming portion was incredibly easy; just make a program to list off a certain number of prime numbers. They also ask questions like "explain inheritance to a 5 year old". That's probably the hardest one. Half of the questions were about whether I was willing to relocate for the summer, where I would like to go and why, etc. They really want to make sure that you want a job with them, which is very appreciated. Very pleasant interview process overall. They called me and told me that I had reached the second stage, but then called about a week or two later and told me I got the internship, so I guess I just must've done well?

Only 1 Teams interview, first part was "technical" which was write a program to find first 100 primes. Then write another program to determine if a number is prime or not. Study that and you are good for the interview, no need for Leetcode. Second part was behavior, I was asked about myself, what I know about Fast, and if I'd relocate. I was also asked to describe how a credit card works to a 2nd grader. The interviewers were ok, it felt very corporate as opposed to a conversation. But it was still easy and wouldn't stress over it.
