Tech Mahindra Tech Lead interview questions

They will complete all the interview rounds and then keep you waiting for offer letter forever.. Very unprofessional and worst hr behaviour.. Even their project teams reached out to me.. These people are cheaters and repeated the things twice.. This lead me to loose one of the job offer

it was around 45 mins. Interviewer asked java questions, aws, devops, servers, general and other questions. he asked to write program, and asked to explain the logic. it was good.
