I have experienced this. My team works in a niche domain and finding people who both have the relevant domain expertise and pass the interviews is hard. I think this is less because of people being unwilling to do interviews and more just inherent noise in the process. It makes hiring especially brutal when 95% of candidates the system throws my way are completely unqualified because they don't have the domain background.

This is a clear and unambiguous downside.

But the presence of downsides is not always a reason to reject a process. A huge upside of the process is that Google enables fluid transition of people within teams around the company. This among my favorite things here and it makes it so that good people with shit managers are not just automatically flung out of the company because their particular team is a toxic mess.
