It consisted of 4 technical round. 1st with AEM, 2nd with Senior Manager, 3rd with Director and 4th with VP. HR was very proactive to provide feedback immediately after all rounds. After last round, they took longer to respond and then gave multiple reasons to reject. They first mentioned lack of enthusiasm and then they said technical knowledge needs improvement. In rest 3 rounds, feedback was excellent. And suddenly, in 4th round, they somehow felt totally opposite. Strange! I was lookinh forward to join the organisation but they probably had other candidate to consider so gave multiple baseless reasons to say no.
