I had one round of in-campus interviews first. Then, I received an email inviting me for an onsite interview.

There were four rounds onsite.

In the first round, the interviewer seemed interested in my projects. He asked me to design a recommendation system for room booking. We discussed features of a room and how to use these features to recommend rooms to users.

The second round focused on technical questions. He asked me about multithreading and locking in Java. I am not very familiar with Java multithreading, so I felt I didn't perform well in this round.

In the third round, he asked me again if I was good at multithreading, and I replied no. He continued to ask knowledge-based questions instead of algorithm questions.

In the fourth round, he asked me some SQL queries, which were quite easy.
