Your Philosophy on Writing Maintainable Code

Question

What is your engineering philosophy on writing maintainable code, and give a specific example where it saved your team significant time or pain?

Areas the interviewer will explore

• How do you name things? (variables, functions, services)
• When do you write comments vs make code self-documenting?
• How do you balance abstraction with simplicity?
• What does "over-engineering" look like to you?

Strong answer signals

• A concrete story where readable code reduced incident time
• Opinions on specific patterns (e.g., "I avoid deep inheritance, prefer composition because...")
• Awareness that maintainability is a team property, not just individual
