Microsoft Intern interview questions

I was contacted by a recruiter from my school. I then did on campus interviews where I signed up for a slot. The interview consisted of a whiteboard session where the interviewer only got around to two questions

They send you a mail 4 weeks after application. Interview process has 3 rounds.The first one is leetcode assignments. The second and the third are face t face interview. Difficulty of leetcode problems are intermediate, so not so much hard.
