ClearSky Logic Project Manager interview questions

3 rounds, HR , Technical Project Manager, and CEO round. All 3 rounds were well organized and people were friendly. Only issue was after 3rd round rejection email just came without any proper reasoning. I had to ask and reply was just via email which was not very clear enough. After 3rd round one would expect to get a HR call and explain why one is not selected. Otherwise all good, and I would have loved to join.
