I applied through a recruiter. I interviewed at EY (Hyderābād) in Jan 2023
Interview
There were total of 3 rounds, 2 technical and 1 HR. Got the mail that I have been selected for the role and submitted all the necessary documents and CTC discussion is also done, At the last moment I have been told that approvals are pending with manager and after two weeks the position has been closed. Didn't received any offer and my time was entirely wasted.
