3 rounds.2 technical and 1 hr.After 2 technical rounds,they interested to hire and ask for documents and slips and call for salary discussion in office.After they arrange hr round virtually and send mail of rejection

It took 3 days, i cleared all rounds. they asked me for all my doc and promised to send offer letter next day. After 3 days they mailed me with confirmation of rejection. I never had this type of bad experience ever in my life. seriously, they are hiring with reference only.
