The overall process involved two technical rounds followed by Hiring Manager round. All three rounds happened for me where I was notified by HR that I have cleared technical rounds. Hiring manager round too went well where a rough figure was mentioned during the round and they mentioned they are interested to fight for the candidate if competing offers arise and that concrete offer will be shared. Suddenly, next week, abruptly my referrer got email that my candidature is dropped. It was not expected, and I was not even notified by the HR even, reasons would be further thing to expect. Sheer waste of time for the candidate and keeping them hope of getting an offer.
