I submitted the application through a refer. Then get an phone interview, asking basic c++ concepts and some basic coding questions, like BST. Then I'm invited to the campus interview, which was my worst experience ever, though not anyone's fault, mainly because of flight delays. They arranged car to pick you up at the airport and give you $100 after the interview. The interview has several rounds, and if you're not doing well, you're taken out immediately after that round, like me. In the only round I'm interviewed, I thought I'm doing all well except for one coding question.
