There were three rounds of interviews: two technical and one managerial. Overall, the interview was easy. You were given a lot of time to solve the problems. The interviewers would present a problem and then leave for 15-20 minutes before returning.

Since I did not have a Java background, I was asked questions mostly on DS, Algo, SQL, and Math.

1st Round: Print unique elements in an array.

2nd Round:

• Scheduling Algorithm question: If given trains' arrival and departure times, provide the minimum number of platforms required.
• A geometry calculus problem.
• Check valid Sudoku code.
• A mathematical number and the minimum time complexity to calculate that number (I don't exactly remember the question).

3rd Round:

• SQL: Get the name of the 10th highest-paid employee.
• Denominations puzzle - medium difficulty.
• Make 100 using four 7s and mathematical operators.
