Had one 90 minute HackerRank test with 4 questions. Two Questions were difficult. The questions seemed too many for the test duration. There were two rounds after. Questions were mostly on system design. The HR called me after the 2 rounds and told there would be one more round on DS and Algo. However that did not happen and when I enquired, I was told it had been postponed and I was never contacted again. Interviewers were friendly.The HR should have been more professional in scheduling the interviews and conveying the result.
