Attended technical round. I got Shortlisted in technical then managerial round happened after 3 working days. I got a mail like I was selected for the java full stack developer position. Then again after one month I got a HR call about salary discussion. They told me I will get offer letter within 10 to 15 days. I waited for that letter, it didn't came. But again hr call happened after 15 days. So nearly I waited 3 months. They didn't release any offer letter. My notice period also done. I put resignation to the previous company because of cognizant offer. Worst experience ever I have. They didn't not give any reply to mails or they didn't provide anything to track the offer letter status.They made me loose my job.
