First round was online test, it did not contain DSA related questions. Second round was technical round, I was asked to code a deletion of node in SLL, then going further, OS and CN questions were asked in easy to medium level, more of CN questions. Next round was manager round, for half an hour, in which they can question about anything in your resume and you should know every bit about all the projects mentioned in the resume, since one of my project was based on SQL database, I was questioned on how to implement payment transactions as a part of db operations, apart from resume they asked one other question - how do I come up with a sudoku solver, I answered telling we can use graph coloring in such and such way, but I wasn't very sure of the full implementation. I was asked if I prefer developer or testing role, I stated my preference to be developer role since it was an internship. I heard two days later through mail that I was not selected for HR round, the offer was bagged by one candidate
