I applied through college or university. There was an on-campus opportunity where Microsoft came to our college and hired 15–16 interns. The first round consisted of online assessment questions, which included two medium-level questions on strings and knapsack dynamic programming.

They asked for an introduction, then started asking questions from my resume about my projects, such as what I had built. Since I had put a chat app on my resume, they asked me about WebSockets, the difference between WebSockets and HTTP, and whether I had worked on AI. Later, they asked me one DSA question, which was a sliding window problem, and then that round was over.

For the second round, they asked me more about my project and user-IT support, which I couldn't answer very well. Then they shifted to a DSA stack implementation question, which resulted in an error that wouldn't run, and I didn't get time to debug it. Another question was on group anagrams, for which I couldn't give an optimal solution either. Afterward, they asked me if I had any questions for them, and that was it. I regret not being able to revise these topics and instead spending all my time studying graphs and dynamic programming.
