1. I was emailed a few very simple programming questions; anyone who has completed introductory programming could probably answer these.

2. I was then set up with an HR person for a few behavioral questions on Skype. It took about 15 minutes. Very good experience, I breezed through it.

3. The next interview was a technical interview with a few behavioral questions, also over Skype. Two technical interviewers asked me questions, and the hiring manager asked some behavioral questions. There were a couple of simple questions: explain the difference between a queue and a stack, then a couple of programming questions that are equivalent to easy questions on coding challenge websites. I breezed through these pretty easily as well.

4. I received a notice that I was moving to the next step and would be contacted by the department for another interview. Instead, I was told a couple weeks later that I didn't make the cut. Kind of confused on that one. The interviews were easy and relaxed, I have a near-perfect GPA just short of 4.0, and I had a lot of finished projects behind me. I suspect that's just how it goes when you're in the same state as Georgia Tech.
