On campus interview. Took 30 minutes. Demo the code on white board. No behavioral, just code. They will give you some arbitrary test cases and let you run them manually to test your code.
Asked a few behavior question first, then proceed to tech part. Started with an easy coding question, finished it, did not have time for the next one. The last few minutes was answering questions from me.
They contacted me first from my university. We had a short phone screen, then they came to my university to interview me. The whole process took about two weeks. I think they were rushed since I've never seen it go by so quickly. The month of recruiting was October.
