Demandbase interview questions

The recruiter reached out to me. I was asked to be open in terms of title. He briefed me about the interview process. The process took 2 weeks to complete. Total 6 rounds. All rounds covered evaluation on Java, scala, spark. Java questions asked were very detailed. The quality of questions asked on Java was good. First round was an introduction call by hiring manager. From second till final rounds all were technical rounds. The fourth interviewer was very full of ego. He wanted to show me how intelligent he is and saw him mocking and laughing at me. I also told him that I have few questions regarding work towards the end of interview but he said he doesn't have time to answer as he has another meeting. It appeared to me from the interview rounds that their culture is not great.

Hr was careless. First introductory call then DS & algo call. Then for coding round they had some junior engg. whose experience were from service industry - he first cancelled the round by joining the round - then when actual round happened he didnt come on camera. He asked to print 1-n using 3 threads, even using one thread, odd using 2nd thread and a delimeter using the 3rd thread. When I coded it, he was kind of raising a doubt how could I finish it without interruption and why am I taking some minutes to modify the program- the interviewer was egoisting, not well versed with CS, he was showing off, probably engineer of his level is given high respect there - so much that they start disrespecting candidates in the interview. He was behaving like a headmaster.
