RapidAI Senior Software Developer interview questions

I was contacted by the recruiter for the job. I has three rounds of online interview with the people from the technical teams. After third round the HR just ghosted me. no feedback or reply from the HR or any mail from anybody.

Quick chat with team lead followed by a 3 hr take home test. Rejected after submitting the take home test without feedback. Team lead warned over the phone that the take home test is a point of contention among interviewers but RapidAI appears to be unwilling to make internal adjustments to make the interview process more palatable.
