When assessing a candidate's experience, look beyond the years they've worked as a full-stack developer. Consider the complexity and variety of projects they have been involved in, the technologies and frameworks they have used, and their level of autonomy and responsibility.
Ask for specific examples of their past work, including their contributions, problem-solving strategies, and the outcomes achieved. Assess how well their experience aligns with the requirements of your organization and the specific projects they will be working on.
