Microsoft Software Engineer Internship interview questions

I interviewed for the internship position in 2024. The process consisted of two rounds. The first round included a technical question focused on Data Structures and Algorithms (DSA), along with a few behavioral questions. The second round varied significantly depending on the interviewer, with some focusing more on system design or technical discussions, while others leaning towards behavioural questions.

OA, pretty easy one, but i dont remember the questions. at the interview i got a graph question: create classes for puzzle pieces and solve the puzzle using graph methods (bfs / dfs)
