A company recruiter reached out for a quick ten-minute call and scheduled a 60-minute technical interview. During the tech interview, I spent fifteen minutes talking about my background to begin. The coding question was relatively simple, but I didn't quite get it due to some small errors in the implementation of checking for wins. The interviewer stopped me after about 40 minutes for additional questions for him.

I did feel that the interviewer was extremely uninvolved when I asked him for help in debugging. If I were in his position, I would have mentioned to the candidate that they mixed up row and col in accessing the board, which is a really trivial mistake.

Code a Tic-Tac-Toe implementation for an N by N board that returns who won or if there was a tie. Input comes from STDIN in the format (row, column).
