I applied through college or university. I interviewed at Cognizant (Calcutta)
Interview
There was two rounds of interview-Technical & HR. In technical interviewer first asked about my self and then told me to pick any two subjects of my interest. I told him c and oops concepts.
So first he asked what is a datatype and what are the data types supported by c.
What is a local variable and global varriable?
What is a function and what do you mean by function declaration and function implementation.
Write down a code to find the 2nd largest element in a array of integers.
What are the main features of the oops?
Explain polymorphism.
What is a constructor and what are the different types of constructors
Final keywod.
I don't remember rest of the questions. Approximately I answered 70% of the questions after that hr round was there. He just asked about myself and what do you know about Cognizant. 3 or 4 more questions he asked. It was more like a discussion rather than a interview and I got selected.
Their server very down on that day, in technical round you will be interviewed by 2 persons ( working professional and hr team member) . For my friends they asked oops concepts,sql, rest api ,etc....
It was online through the laptop. Depends mainly on the interviewer how difficult the questions are. Some were asked Palindrome, some were asked trees, lol. I had to go to Noida for the process.
