Cognizant Data Scientist interview questions

It was an easy interview with questions asked from dsa (basic level), some core subjects questions and puzzles were asked. There was only one technical round of about 20 - 25 mins.

Questions were based on projects and internships mentioned in the resume. Then some questions were also asked on topics such as Data Structures and OOPs concepts. My questions were based on Polymorphism, its types and I was also asked to code an example for it.
