This was a terrible experience overall.

Very poorly orchestrated interview process right off the bat. I was directly contacted by the hiring manager for a phone screen. A week later, the recruiter informed me that I was invited onsite for six interviews (1 hour each).

After spending the whole day onsite, the hiring manager let me know I'd know the outcome the next day. However, the next day, the recruiter asked me to come back for two more interviews onsite, with no explanation for why, with whom, etc. The communication was very rude, and there was no attempt to accommodate timing either. One would assume they would structure the interview panel to include all interested teams in the first place, not keep calling a candidate back for additional team interviews.

Anyway, after spending nine hours total (including one hour over the phone), these individuals didn't even have the decency to get back with a response or follow-up. It's been over a month.

Really disappointing process and interactions. I will obviously never interview with them again and would actively encourage my peers to never interview with them either.
