What this interview will probe
Work across Mercury's stack, writing Haskell on the server and React with TypeScript on the client to deliver complete product experiences in the banking dashboard, from account flows to dashboards startups use daily. You'd own features from API design through polished UI, balancing performance and product craft. An interview would likely cover building a small full-stack feature, designing a clean component and state model in React/TypeScript, and wiring it to a well-typed backend endpoint while reasoning about edge cases and error states.
