Interview had 3 Rounds. 2 technical and 1 techno-managerial. I was told there would be one more round with some managers in USA. After a week I was told the position has gone on hold due to some internal issue. I read several such experiences where Epsilon interviews candidates and then cancels the position. This does not seem like a professional way of working.

2 technical rounds, between which I was made to wait forever. Was told that I cleared them, and there would be a managerial round. Kept waiting for a month, with various reasons cited by recruiters. First it was the team being busy, then the HR team being on leave. After a month, was told my "candidature would not be taken forward", but no concrete reason was cited. I think I deserve to at least know the reason why my candidature was not taken forward. Anyways, thanks for wasting my time!

Written test followed by f2f. Written test is like you applied for some service company. An interview was scheduled on a weekday. It looks like a drive on a weekday as there are 20-25 candidates came for an interview.
