I think there’s (unfortunately) a need for a low-effort high-pass filter for candidates because there are so many utterly unqualified candidates chasing the dollars that a software job can bring. I don’t blame them, but I also think the bottom 10% of all potential programmers is way over-represented in the applicant pool and finding a way to filter them out effectively has value.
It doesn’t have to be leetcode, but it does have to not be “have an engineer spend an hour with everyone”
