Cognizant interview questions

The interview was about 30 min long focusing only on DSA, SQL and OOPS concepts. It was held through superset on campus. Before it there were 2 assessments one technical assessment held on campus and other a communication test held online.

Interview process was really easy and professional to me . After interview got offer letter in 15 days . Changed joining date as per my request as suggested date i wasnt able to joined. Job description was a bit different than we discussed in interview
