Apollo Global Management Full Stack Developer interview questions

Scheduled a Monday morning interview with me, and requested I complete a take home assessment. I spent several hours over the weekend completing an (in my opinion) overly intense coding assessment consisting of 4 complicated and involved problems (all Leetcode hard level). The assessment was capped at 4 hours, at which point my code was passing ~70% of the test cases, I think to comfortably complete and debug for a perfect score would have taken at least another hour or two. They then canceled my interview without sending communication. Ultimately very frustrating and a waste of time.
