First, there was a small intro round with some tech person where a few JS questions and design patterns were asked. Later my application was moved to an in-person interview and I was asked to draw my current project architecture and questions were asked around it, later few basic JS questions were asked, and one DSA problem (merge overlapping intervals) needed to be written on white paper the communication of the interviewer was very bad, where I asked few valid questions for the given input and no proper response from the interviewer (as I have practiced this question, so I have written the solution, as I intentionally made a syntax error where i thought the interviewer would find out and can be discussed, but, unfortunately, he wasn't able to find), after this round, there was another round with engineer manager where the discussion is around few js concepts like promises, previous projects, and AWS. After a week I tried to reach out the HR over call regarding the status of my application but the HR number was completely switched off, I dropped a mail too but no response.
