How would you lead a team to improve quality?

Behavioral / Tech Lead Leadership

You are acting as a Tech Lead (TL) for a small cross-functional team (e.g., 4–8 engineers + PM/Design/QA) working on a consumer product.

Part A — Leading execution

• How do you plan work, delegate tasks, and ensure accountability?
• How do you handle underperformance or misalignment within the team?
• How do you communicate progress and risks to stakeholders?

Part B — Improve product quality

The product has quality issues (e.g., crashes, latency regressions, bad recommendations/search results, user-reported bugs).

• How do you define and measure “quality” (user-facing + system metrics)?
• What is your approach to diagnosing root causes (data, logs, experimentation, on-call signals)?
• What process changes would you introduce to prevent regressions (testing, monitoring, release gates, SLAs/SLOs)?

Part C — Landing a project with measurable impact

Pick one project you’ve led (or propose one) and explain:

• Problem statement and success criteria
• Your execution plan and trade-offs
• How you influenced stakeholders and unblocked dependencies
• What the measurable impact was (or would be), and how you attributed it

Assume you must balance short-term delivery with long-term quality and team health.
