Interview Guides
You are the EM owning a new API for a B2B SaaS platform that will be consumed by internal services and a small set of external partners. The API needs to support a fast-moving product roadmap, but it also has to be stable enough that partner integrations do not break when the backend evolves. You have to make decisions about request shape, authentication, pagination, error handling, versioning, and observability while balancing developer experience against implementation complexity.
