The first round was easy. The interviewer was knowledgeable and asked questions from basic OOPs concepts and current project architecture. I cleared the first round but could not clear the next one.

The second round was conducted by two people: one man and one woman.

• The woman asked some basic questions from a sheet. She didn't seem to understand the answers, merely checking if they matched her own.
• The man had a lot of attitude and asked strange questions, such as "How did Microsoft implement the List collection class? Write the code for this!" His English was poor (he kept saying "actually" in every sentence). He was unable to express the questions he intended to ask clearly and seemed irritated when I tried to clarify them.

Overall, the interview process was fine. I expected better interviewers in the second round.

How did Microsoft implement the List collection class? Write code for this.
