The interview process involved one assessment, one phone screen, and one power day, as mentioned in other interviews. The difficulty was fairly standard. However, I had a negative experience with one of the interviewers during the system design round. They were condescending and pressed for answers, even when I stated I didn't know.

Recruiters were disorganized and rude. They missed scheduled calls five different times and called me during times I explicitly stated I wasn't available. During the offer call, the recruiter was condescending and rude, did not acknowledge my concerns, and even expressed frustration when I tried to schedule calls with other team members or the hiring manager. No other company had shown me this much disrespect.

The team I met was, overall, great. I declined the offer due to my experience with the recruiters. It was clear they saw me as a number or metric, not as a person, which spoke volumes about the company culture.
