At the risk of being that guy, is the _entire purpose_ of the interview process not to exclude engineers , or conduct a purity test?
Surely the most bias free way to hire would be to say yes to the first applicant. Of course this excludes engineers who are busy and were not able to apply first... so perhaps the randomth applicant gets sent a "youre hired".
I mean. Hey maybe its a better process. We have yet to see some metrics on this.
