Cognizant Associate (Pl/SQL Development) interview questions

The interview process was highly uncomfortable. Though not a walk-in, there were a lot of people who were scheduled to interview on the same day. I was told to report at 9am. I reached by 8.30am, but wasn't called for the first round of interview till after 1pm. The HR interview was soon enough. I was told I was selected and that I would be mailed the offer letter within 2 weeks. Received the offer letter only after 2 months. The experience with the HR coordinator was horrible. He was least interested in responding to any questions/concerns. Overall, Really unprofessional experience. Had to turn down the offer due to HR's unprofessional attitude.
