Asked me to spin up a new React environment and program Minesweeper on the spot in TypeScript and React and would not answer any of my questions or help me when I was stuck on small syntax issues. I have never been in an interview with a person who was so completely silent, it was really weird. I was talking the entire time and maybe on 3 occasions, he would mutter a one or two-word response. Stopped me before we even hit the time limit and told me I would not go to round 2 of the panel interview. Clearly what they're looking for is someone who has created this game before and has memorized a solution.
