Tech Lead Interview Plan: Assessing Technical and Leadership Skills

Now that you know the important skills, here’s a simple plan to help you run your interviews:

  • Round 1: Screening (30 – 45 minutes)
  • In this initial round, focus on understanding the candidate’s background in both technology and leadership. Start by asking about their previous roles and the programming languages and technologies they have used. You should also explore their experience with leading teams. Ask questions like how they ensure the quality of code produced by their team or how they handle prioritizing tasks among team members. The goal is to see if they can clearly explain their past experiences and demonstrate effective leadership skills.

  • 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. Look for clear examples that show their ability to lead a team effectively and handle various interpersonal challenges.

  • Round 4: Final Review with Engineering Manager / CTO (45 minutes)
  • In the final round, assess how well the candidate fits with the company’s goals and culture. Talk with them about how they would align their role with the company’s objectives and their approach to ongoing learning and improvement. Ask how they would integrate into the company and adapt to its environment. This round is crucial for ensuring the candidate’s technical skills and leadership qualities align with the company’s needs and culture.
