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.

Was given a function q(func) which accepts another function as input. Each time this function is called, it will execute the pass in function after 3 seconds. So, if it is called 3 times, q(func); q(func); q(func); the func passed inside will only get called after 3 seconds and the second one will get called only after the first one completes and so on.
