Cognizant Program Analyst Trainee interview questions

As I'm from ECE stream,the interviewer asked many questions which are related to my field(digital electronics, microprocessor and micro controller, digital communications) and less coding questions. He asked me to solve few aptitude questions and I solved it.

Interview span was around 20 mins, First of all madam asked for introduction then give one simple code( just to check approach) then asked me some OOPs concepts and data analytics because it was mentioned in resume followed by some HR questions, finally madam ask me for questions from my side and that's it.
