Round 2: Technical Evaluation (60 minutes)

This round involves a practical assessment of the candidate’s technical skills. Set up a coding challenge or problem-solving exercise to test their expertise. For instance, you might ask them to design an API rate limiter or discuss their approach to refactoring an old codebase. Pay attention to their understanding of design principles and how they apply their technical knowledge to solve real problems. This helps determine if they have the right technical skills for the role.

Round 3: Leadership and Communication Skills (60 minutes)

Here, evaluate how the candidate leads and communicates with their team. Discuss their leadership style, how they resolve conflicts, and how they make important decisions. Ask them to describe situations where they had to manage disagreements between team members or make tough calls.
