There were several rounds of interviews.

Despite the fact that I said I didn't know c, the interviewer proceeded to ask me a very long series of inane c syntax questions. Truly the most ridiculous interview I've ever had.

She didn't bother to even ask me to solve any problems, only to predict the output of some small programs in c. It was also a phone interview, so she had to tell me character by character each program. What a waste of time.
