Microsoft Software Engineer(Internship) interview questions

the first step was a LeetCode test, and the second was an HR interview, which was normal, at some point the interview was in English. unfortunately, I didn't get an offer since I was in my final semester at uni. the interviewer said that the reason for that is because the contract requires at least 3 semesters and it's mandatory, in other words entering this intern position with only 1 semester left would have caused a contract violation.
