What does adversarial mean in this context? That I disagree with the original poster? > In my experience, I can gather more information about a candidate's ability in just 15 minutes talking 1 on 1 with them rather than hours of Leetcode busywork This is your perspective as someone doing hiring. My perspective is from someone being hired. I really don't think leetcode is that difficult all things considered so a system based on leetcode is just not that bad in my opinion. It's really not that difficult, there is a set of 15 or so algorithms that are all 40 or so lines long and you just need to memorize them to the point of instant recall. Now you can get hired almost anywhere.
