There are 6 rounds of interview, first round interview is technical and case study related. After that they called me onsite for 5 round interview, the interview was good. After 2 days they reached out to me and said I have the offer, and I also discussed my salary and start date as well. They said they will send me offer letter within 2 days, but still I didn't receive any offer its completely strange and weird if they do not want to take a candidate why did they call for interview and why did they email me that I got into the position discussed salary and then no response, completely waste of time, unprofessional team, and they wont even reply to my email, for first one week they gave some sh*t reasons and apologized for delay at end they stopped replying.
