Karza Technologies Python Developer interview questions

Before my first interview I had seen glassdoor for karza's interview process and came across many claims stating that they ghost candidates etc . My experience was similar . First interview was telephonic 30 minutes call , bunch of very easy ds algo questions , db question etc . 2nd round was totally ds algo live coding round , 3 questions were asked and I coded all of them perfectly . Now comes the 3rd interview(telephonic) , the interviewer himself has less knowledge about psql vacuum and argues with me , next has no clue about consistent hashing , so after 20 mins he declares that interiview is over and will share the feedback with the HR . It has been 3 weeks now , they is no update on my candidature status . Atleast a mail saying that I am not selected would have sufficed ,but they do not care , also after answering so many ds algo questions correctly , I am rejected due to interviewers arrogance . Atb finding the right candidate .
