You're not selling this to interviewees. So their sentiment - that is, my sentiment - ultimately doesn't matter.

However, I would wager that a lot of good software engineers would view this as wildly disrespectful of their time, and would refuse to engage with this; it would be a filter for engineers who for whatever reason cannot say "no" to this - more desperate, more junior. It might impact the actual customers, when their talent pool starts looking shallow and full of algae.
