I applied for the interview online, and after a couple of days, I got an email for scheduling a TA interview. I have attended it with one of the TAs. It is mostly smooth. She first introduced herself and asked me a single question: Tell me about yourself." That's it, and she told me that she would forward this to the manager and get back to me. Since, then I never heard anything back from her; I guess she forgot my email to revert back, lol
