The question was verbatim from LeetCode's "Meeting Rooms II." I solved the coding challenge in three different ways.

The interviewer called my solution a "fluke" and suggested a nested while loop, which I stated was incorrect to use.

The interviewer also made errors with the annotations on a sorting list comprehension.

I felt the interviewer was extremely rude.

I would avoid this interviewer; Tina.

Given an array of meeting time intervals, intervals, where intervals[i] = [start_i, end_i], return the minimum number of conference rooms required.
