HackerEarth test followed by one technical coding interview, which was very simple, followed by a design round and a Hiring Manager round.

The first round was very easy. You just had to give the algorithm and not necessarily working code. Four questions were asked in this round, and I was able to answer all of them.

The second round was supposed to be a design round, but the interviewer did not join the scheduled call three times in a row. I was kept waiting on the call forever, and only after contacting the recruiter did I come to know that the interviewer was on leave.

The third round was a Hiring Manager round. The hiring manager seemed pretty uninterested in the candidate or the interview right from the beginning. He was putting the candidate on hold and chatting with someone during the interview. He seemed very arrogant and did not even seem to care about knowing the candidate's profile before the interview.

Design round: Microservices architecture vs. monolithic architecture.

This was a very vague question related to design. To be frank, I did not get the question, and the interviewer was very bad at explaining the question and the requirements.
