Software Engineer Interview Questions & How to Answer Them

4 questions you're likely to get for a software engineer role, with a tip on what actually makes a strong answer.

Question 1

Walk me through how you'd design a URL shortener.

Focus on requirements clarification, data model, and scaling considerations - interviewers want your reasoning process, not a memorized answer.

Question 2

Tell me about a time you disagreed with a technical decision.

Show you can advocate for your position with data while still committing to the team's final call.

Question 3

How do you approach debugging a production issue you've never seen before?

Narrate a structured process - reproduce, isolate, check logs/metrics, form a hypothesis - rather than jumping to a guess.

Question 4

What's a project you're proud of, and what would you do differently?

Pick something with real tradeoffs, not just a win - self-awareness reads better than a flawless story.
