The HR reached out to me for the interview. Everything was communicated through emails - which made the process very slow. It took about 6 weeks to complete 3 rounds of interviews. 1st round was discussion on hashmaps which went pretty well - the interviewer was very much friendly and was understanding my thoughts. This led to the second round of interview. 2nd round was the discussion on API design which was also related to airbase product. We had discussion on designing the API and storing the data in the database as well as the communication of frontend and backend through web sockets. This round also went well and which led to the next round. 3rd round was on system design - designing a twitter API and model to handle concurrent requests - we had discussion on this - the interviewer gave some hints on the answer he wanted to get from me and at the end we arrived at the optimal solution. After this I got a response - that we can not go ahead with the candidature as of now - which was very disappointing as the interviews went pretty well. On asking the HR about the feedback as to why I was rejected - they didn't have any answer and didn't respond for that. I would suggest for the candidates to keep giving interviews in the middle as the airbase process is really slow and they might reject you even if your interviews went well. For airbase I would suggest to make the process a bit faster and give proper feedbacks to the candidates.

First round is with engineering manager. He asked about recent work n challenges i have faced. Second and Third are technical round. Gave one assignment to write better loader logic in react seperately apart from interview
