Initially I got a call from their side had little 1st round of technical interview at the same moment and they scheduled the 2nd round of Technical interview after 2 days for which I got result within 30 min after the interview. Then they scheduled the 3rd round of Technical interview within 4-5 days for which I got result again in 30 min. Then finally I had HR interview and in next 3-4 days I got the offer letter. Note: All the interviews were video interviews through zoom meeting.
