The interview is certainly useful in that it reflects Stripe's aspirations as a product team. I would have found this interview much more interesting if you had been able to go into detail about the reality of working on a product team where you're holding yourselves to a set of mutually incompatible constraints -- what tradeoffs you tend to make, how you think about making them, what are the common failure and success modes. Maybe a good follow-up post; consider this a single reader's suggestion, not a demand :)
