Answer some questions during the career fair, and get an email for interview a week later. The interview was on campus and two person interviewed me. They asks some basic question but at that time I haven’t learn them yet.

Phone call interview with a Software Engineer. He had me ssh into their system and then asked me some coding questions in C. After that I was brought to HQ and given the offer letter. Interview process was smooth and it was refreshing communicating with an engineer from the beginning rather than going through a recruiter.
