The worst interview experience of my life till now. The process consisted of 4 rounds initially: 3 technical and 1 managerial. After every technical round, I got a callback saying the feedback was positive. After the 4th round, they ghosted for a week.

I called HR and was told that all rounds were considered and feedback was negative. No mention about the actual feedback.

After 2 more weeks, I got a call and was told that another team was interested in my profile, so there would be 2 more rounds (1 technical and 1 managerial). The 5th round was the easiest of them all, with 4 very basic questions asked, and I answered correctly. I got a mail after a day that I was rejected.

It's clear they are looking for something they themselves don't know about. After all those rounds, I was still blank about where I went wrong and what I should improve. Totally wasted my time and theirs as well.
