It was a campus placement.

The process consisted of an online test, followed by a group fly round, and then on-campus interviews.

1. Online Test: It had three coding questions. The test was of moderate difficulty.
2. Group Fly Round: Then there was a group fly round on campus, where we were given two questions. We had to solve and code the solutions on paper. They then evaluated and shortlisted candidates for interviews.
3. Interviews: There were three rounds of interviews. Two were purely technical, and the last one was a technical cum HR round.

Q1: Given a shuffle function that shuffles 52 cards, you want to check whether the function is a good or bad shuffler. You can do this by performing 10 million (or 100 million or 1 billion) shuffles. Now, provide an efficient strategy to perform this and suggest an efficient data structure.

Q2: This was mainly HR questions. Some of the questions were: What do you want to do in life? How did you get AIR 737 in JEE? What are your strong points/skills?
