Idk, if your aim is to find the "best talent", then what's the chance that they stumble along and you treat them like shit?

That's what's going to happen when you say "out of this other group, this 99% of people who I didn't want anyway, many of the Google Voice people were fraudsters".

Same thing for asking people to reverse a linked list on a whiteboard, or getting them to re-do their résumé, but in your HTML form instead of just emailing you their pdf. If you do ever get your dream candidate, you've pissed them off.

With most interview processes, your aim is to have a high degree of certainty that you will find someone in the top 1% or so of people, not to find the absolute best person. Given that, arbitrary filters that save your time are very much worth it.
