VERY unprofessional interview process.
I applied with a referral in December and got an invitation to take a 7 question debugging and 24 question reasoning test. 2 days later I was invited to take a 2 coding question test. 2-3 weeks later I received an invitation to the final round phone interview. I was given about a range of a week for possible phone interview days, the last day of which was a Wednesday. I picked many available hours on each of those days, and specified that I had an exploding offer the very Thursday after that Wednesday, so that I preferred an interview ASAP. They picked my interview to be the very last day, Wednesday.
Wednesday comes, and 15 minutes after my interview was supposed to start, I get an email that my interviewer has cancelled on me. Again, I have an exploding offer on Thursday so I end up rescheduling for later that same day. 20 minutes after my NEW interview was supposed to start, I finally get a call from my interviewer. That is 20 minutes that I lose off my my total interview time because my interviewer had to be punctual to his next interview, because for some reason it wasn't important to be punctual to mine. The cherry on top was that there was constant static on the phone and my interviewer couldn't even see what I typed and had to disconnect and reconnect constantly because of technical problems on his end. Got the rejection email 1 week later.
