I think an ever bigger evil is companies who do not calibrate their Leetcode type tests to their hiring needs. I was given a take-home test few years ago by a well-to do medical software company based out of Verona, WI. Their programming test had a question from past ICPC.
Typically Olympiad questions takes well-to-do teamwork & few hours of brainstorming - not a 30min timed test you give with a proctor watching your monitor
Epic doesn't expect that you will finish every question on the exam. That's actually the point of giving harder questions: the ability to calibrate against the entire candidate pool. If the test is so easy everyone aces it, how is that calibration going to go?
In a 50 min test with 10 min MCQs and two timed questions, where one question is a ICPC derivative question & the other one is refactor a pseudocode similar to MUMPS language, what CS talent is it exactly testing?
I don't mind writing MUMPS if I was hired, but the test is not my ability of understanding MUMPS-styled syntax or predicting the win percentage in some chess layouts without using MCTS.
