I got an email from HR after I applied for this position on University Portal. Scheduled a phone interview next week with another Software Engineer. It went well, basically asked to introduce myself followed by couple of question on data structures & algos. Got a mail from HR for the onsite interview couple of days later.

Scheduled it the following week. Was given a test which the standard process I believe with 40 mins to complete it. After 40 mins the hiring manager came in took a look over the test, didn't go through the code. He was interested in the OO design ques in the test. Started asking about it & later he got into logic ques. All he wanted to see is how good my logic is, which if I would have been prepared for, would have been good. It didn't turn out well. The next couple of rounds were just the oral technical questions & behavioral. Those consisted of questions from databases - joins, groupbys & oops concepts etc.
