Perguntas de entrevista de vagas de Software Developer da empresa SentinelOne

I got a call from HR where she asked me about my background and skills and scheduled the first round. First round was a DSA based round where they asked me variation of tree path sum question, which I took bit of time to answer. I thank that still they qualified me for the second round where it was Go LLD round where question was to parallelise a serial execution of code, which I feel I did very well and interviewer was also happy. After that I got to know that the feedback was negetive which I dont think should be a case. I think it was my notice period which they were bothered about and I would have appreciated if they were more straight forward on the rejection reason

3-4 rounds Technical Screening, Coding Round 1, Coding Round 2, HR Manager Round This was one of the worst experiences I have had in my entire career, the recruiter asked me to give dates for interview and I did. I completed the first round, the interviewer joined 20 minutes late, and asked me one coding question, which i solved, interviewer was disinterested the whole time, I got the working solution, gave optimizations. The interview ended 15 minutes before the expected time, so the whole interview was just 25 minutes. Immediately I get an email saying I was rejected , when enquired why, the HR got angry and started yelling at me. Saying they know what they are doing, without giving any proper feedback. They do not care about the candidate, and only waste our time. This was one of the worst experiences I have had. After investing weeks of preparation and doing well in the interview, the minimum they can do is provide actual feedback on why candidature is being rejected.
