Screening interview with a recruiter followed by a technical interview soon afterward. The interviewer was totally uninterested. Did not want to engage at all, even though it was presented as a pairing interview. The problem was a Langton’s Ant similar to what you find on LeetCode.

My personal impression was that there was 0 intention of hiring people like me from the very beginning. Most of the interviewers were busy doing their own stuff on the side and sometimes I felt they didn't listen. One guy was typing and laughing all the time in front of me while we were discussing serious stuff. 7+ hours of my time are just wasted with this nonsense. I wouldn't spend energy on these guys because it seems they are not serious at all. Also, the fact that managers are not required to code but have to pass 1-hour hacker-rank coding interview is a bit controversial.
