Right, so then the question is if the other processes currently in place serve as mitigating factors to the inadequacy those qualifications present to the selection system's efficacy. I'd argue that they don't, in which case you're spending a lot more time and money for the same results. If they do, then would fixing the qualification issue be less expensive than interviewing et al.? Again, assuming that you have a choice of similar outcomes at different price points.
