the problem with the interview process is that it is unfair, not properly capturing the actual qualifications and testing the wrong stuff. the complaints here are that this tool does not properly capture the actual qualifications either, and therefore it suffers from the same problem, just in a different way. it may work for a few people, just like the interview process works for a few people, and it may work for a few use cases (like finding a FOSS developer) but it doesn't provide a solution for the interview problem itself.
