2. He asked me to give an approach to sort 1 million strings, I have answered them the solution using the Merge sort where the comparison function is altered and another solution with Tries.
3. Later he asked me if the system has limited resources what will you do.

1. The written test consisted of 20 MCQ questions on C, CO and OS. The level was intermediate and most of the questions in OS and CO were previous years GATE questions.

3. The next discussion was on how to do exception handling in C. I answered him that we can do with If and Else. Also an approach for handling dangling pointers and memory leaks.
