At 0-to-1 companies, alignment and enthusiasm is so important that anything other than "Hell yes!!" is a "No."

The candidate should be saying not "you guys" but "we" by the third interview.

The company should do an anti-sell at the end to make sure the candidate still wants to come even if they tell them all the reasons they shouldn't.

That gives a gauntlet that makes sure only the most aligned and enthusiastic join.

When everyone on the team is aligned and enthusiastic, it is superlinearly more powerful than if only most people are aligned and enthusiastic.
