Do a Codesignal/Hackerrank having to do with intervals. After I finished, I put the question into an LLM (from memory) and it kept suggesting the same approach I used. Unfortunately this was not enough to pass half the test cases. Funny thing is I passed the assessments at other companies like Coinbase which pays 1.5-2x of this company. No idea why they need such a hard assessment that I still have no clue how to solve. Would not interview again or recommend to anyone else.
