Extremely poor. The interviewer gave a coding question and specified it should be solved in O(n) time and O(n) space complexity within 10 minutes, with code. Even after clarifying that O(n) space means I could use extra space of O(n), he confirmed it. Given the scenario, I was figuring out a solution in that direction only by using extra space, while vocally explaining my approach on a shared screen. At the end of 10 minutes, he said I couldn't use extra space and kept bugging me about the time. He said, "You have 5 more minutes; write the code," even though I was not done with the dry run of my approach. Within 15 minutes, he had annoyed me so much that I lost interest in the opportunity and asked him to end the interview. Because if the interviewer himself does not know the basics of DS/Algo and will be judging on it, imagine what it would have been working in a company with such employees.

Move all negative integers to one half of the array.
