User and Developer Needs Questions

Assess how product and architecture decisions balance user and developer requirements with technical feasibility. Topics include gathering and prioritizing requirements, negotiating trade offs between desired user experience and implementation complexity, designing alternative solutions to work within constraints, and communicating architectural implications to product and engineering stakeholders. Interviewers may probe how candidates translate user journeys into technical requirements, how they evaluate feasibility and effort, how they propose product level workarounds for platform limitations, and how they ensure the architecture enables desired user and developer workflows without causing undue technical debt.
