I submitted the application through a referral. Then I got a phone interview, asking basic C++ concepts and some basic coding questions, like BST.

Then I was invited to the campus interview, which was my worst experience ever, though not anyone's fault, mainly because of flight delays.

They arranged a car to pick you up at the airport and gave you $100 after the interview. The interview had several rounds, and if you were not doing well, you were taken out immediately after that round, like me.

In the only round I was interviewed, I thought I was doing well except for one coding question.

If a function returns itself, what will happen if it's called?
