there are two rounds, and the first one is 1 to 1 interview, and HR just asked some basic programming questions, like how to reverse a string, and also asked some about my projects. For the next round, two HRs asked me about the programming knowledge again, and also tested me about how to reverse an integer. The interesting thing is that there was a logic puzzle for me. I was kinda stessed out at that time so that I was kind stuck on this problem. I was notified not to get that intern a few days later by E-mail.
