Approach to giving feedback (both positive and developmental), conducting performance reviews, managing underperformers, and dealing with difficult situations. Ability to be direct while caring about people. Systems you use to track performance and career development.

Approach to building balanced teams with mix of experience levels, skills, and perspectives. Understanding how to structure teams for success. Scaling teams from small to large. Avoiding team fragmentation and maintaining team cohesion as you grow.

Approach to creating environments where people feel safe to take risks, speak up, and fail. Understanding importance of diversity, inclusion, and belonging. Examples of how you've built strong team cultures.

Concrete examples of how you've helped engineers grow their skills, advance careers, and take on new challenges. Approach to identifying skill gaps and creating development plans. Experience growing engineers from junior to senior levels. Specific frameworks or programs you've implemented.

Your approach to identifying top talent, defining role requirements, structuring interview processes, and assessing candidates. Ability to articulate traits you prioritize like learning ability, ownership, problem-solving, and cultural fit. Experience scaling teams while maintaining hiring bar quality. How you collaborate with recruiters and cross-functional interviewers.
