Design a login system for all of Stripe's client facing sites.

"The difficulty was not in the technical, but in the behavioral questions. It seemed like there was a hidden rubric beyond the basics of getting things done that were not necessarily apparent at first glance. Perhaps the role of the FDE is to take in social cues and have an instinct with human interaction that they're judging for here. It seems like they really deeply care about why you want to join the company and the team. It's not really something you can cosplay because they will drill you with different questions from multiple interviewers. I love Stripe as a product isn't going to suffice. Perhaps read their blogs and other online resources about the company culture. They seem to highly value people who work autonomously to scope, design, implement, and deploy solutions while also doing a bit of project management for the parts of projects that do require more resources."
