I had applied in the career fair and I got a call within 10 days. The phone interview lasted more than an hour and was a shared screen coding interview. I was told to write some code for some basic C concepts like pass by value and pass by reference. It was followed some questions on dynamic memory allocation questions. The interviewer was polite and helpful. In the end he asked a few questions on some basics of Python programming but couldn't ask much because of the time constraints. Unfortunately I got a reject saying that my C skills are good for a new college grad but they require someone who has worked a lot more on C programming than I have. In short they wanted someone who is more experienced.
