Yellowbrick Data interview questions

Applied on company's website and first round is a HR round then hiring manager round and then 4 technical rounds. The coding rounds are living coding rounds only c++ and java is allowed. (Avoid don't apply the interviewer were very friendly but I was misguided by the hiring manager and the recruiter I was told the interviews will be on multi-threading but in reality it was all on DSA. I felt like I wasted a lot of time while preparing for them but in the end the didn't ask any questions on concurrency while the company is a startup the engineers look passionate). Feedback to recruitment team: Be transparent about the interviews don't missguide the candidates.
