Only got through the first round. I talked to the HR recruiter who was super nice and informative. I took a quiz after the interview which needed to be completed within 1 week. A few days later the recruiter emailed me and said the hiring manager was going to pursue a different candidate. I asked for feedback on why I wasn't moving forward and never got a response.

Not well designed. Actually no design at all. 12 minutes of talk with HR including greetings and talking about the assignment (5-6 minutes). Given a huge & huge assignment that has taken couple of days (4 total days...) to finish then even not able to talk with hiring manager. I was told there are better candidates..
