I got call from Tech M HR for the interview. Interviewer joined late and then he asked few questions related to my work and past experience. Next day I got selection email from tech Mahindra that I got selected and I have to submit documents. So I have submitted the documents next day. After few days, I got call for HR discussion. HR told we will send you the offer. But I did not receive! I also emailed them asking about the update. But no answer. I also called her. But her phone was switched off. Then after few days, recruiter emailed that they hired internally. They don't need me anymore.
