Spoke with recruiter over the phone. Then spoke with team of senior engineers and management. Asked a few questions regarding my experience working and educational background. HR e-mailed me the next day with an offer. Declined because (1) was currently in masters program (2) commute was 90 minutes each way (3) required hours were 8 am to 5 pm. It just seemed like a like to juggle at the time. Under different circumstances, I certainly would have accepted. It was a very positive interview process.
