Prepare a useful brief
Describe users, core journeys, platforms and integrations. Distinguish a specialist task from a complete product engagement. Share the expected budget framework and delivery constraints where possible. A clear brief helps candidates explain their fit and avoids comparing estimates based on different assumptions.
Evaluate evidence consistently
Ask about comparable projects, the person’s contribution and the reasoning behind technical choices. Discuss testing, accessibility, maintenance and release work. Review a sample of documentation or a representative milestone when appropriate. Technical questions should relate to your product rather than become an unrelated list of framework trivia.
Secure the collaboration
Clarify availability, communication, payment and ownership. Confirm access to code and project accounts, and plan for continuity if the engagement changes. A small first milestone can check the working relationship. Select the developer or team that can explain progress and leave a maintainable product, with expectations recorded clearly.
