The interview was more casual than I expected and lasted about 40 minutes in total. The first 10 minutes were general questions, nothing technical. Basic questions about hobbies, college and work experience. After that there were some technical questions but nothing too specific. A topic would be picked and I was asked to tell them what I knew about it. Then there would be some follow up questions based on my answers. The last part of the interview was a coding part. I wasn't asked to write any code but I was given some code and asked to go through it and say what it did and then pick out any problems I could find. The sample wasn't that complicated and some of the problems were obvious (bad variable names and commented out code).
