I applied through the university career fair in mid-September and got the first-round interview in late October.

The interviewer asked me two questions, both of which were not hard and I had seen them before. The first was maximum subset sum, and the second was to write a program to transpose a matrix. I answered them correctly and quickly.

The interviewer then asked if I had seen similar problems before, as he thought I answered them "Too quickly and correctly." I didn't want to lie, so I told him the truth that I had indeed seen them before. He said nothing.

A few days later, I received an email stating that I performed excellently in the interview, but the quota of internships for my university was full. I am not sure if Microsoft was just comforting me or if he truly thought highly of me. However, the fact is, I was rejected.

Nothing, all the questions were very easy.
