I fear that earlier stage companies will read posts like this and implement it blindly without considering the big picture, which is:

- Stripe is a large and resourceful company with a relatively large engineering team. They can afford to have people focused only on things like this.

- The demand to work at Stripe is high. Therefore they can afford to have a long, grueling interview process. Most engineers will not want to go through a 7 step hiring process at a low prestige company.
