I sympathize but I'm not sure this is the hill to die on. As a potential employee I'm looking for the best company to join for myself, and the likelihood that I will enjoy working somewhere has very little correlation to their recruiting/interviewing practices. So if I want to work somewhere I'll jump through their hoops (within reason), but I'll also be keeping an eye out for red flags from engineers and managers I talk to, because the downside of an annoying interview that is not to my taste pales in comparison to the downside of accepting a job and then discovering the work environment is a tire fire.
