Cognizant Programmer Analyst Trainee interview questions

Simple process. Took one day. Aptitude test of moderate difficulty but short on time. Easy interview questions on basic HR and communication. Little technical knowledge of own subject could be asked.

Initially there was an aptitude test, after which around half of them were shortlisted. Further, the company officials split the shortlisted candidates into groups of 4, each consisting around 10 candidates and one by one the candidates were interviewed. My interview was not quite detailed, as in the interviewer started with questions related to my education and the projects I had worked on during my Bachelors', after which he asked the standard question as to why do I want to work for this company. The decision was conveyed to me within 2 weeks of the interview.
