Microsoft Software Developer Internship interview questions

did a virtual interview and went through 2 questions. only got through one. I applied through recommendations from fellow students early in the process before major career fairs which were nice. The interviewer was nice but problem difficult.

Did online coding test to get past to the first interview. Got through to the interview - got asked questions about previous experience, explain programming concept to a child, design question. Said they would hear back in a week, but had to send a reminder e-mail and got rejection e-mail approx 3 weeks afterwards.
