These are real, level-calibrated questions a Senior Software Engineer candidate with 13+ years of experience should expect. Prepare a specific story (STAR format) for each.

1. 1Walk us through your 3-year vision for System Design in our industry. What changes, what stays, and what investments unlock it?
2. 2Tell us about a Microservices bet you made that took 18+ months to pay off. How did you justify it to leadership while it was still ambiguous?
3. 3How do you coach staff-level peers on AWS when you're often the most experienced person in the room?

1. Match the level of scope: Show direction-setting. Bullets should reference long-horizon strategy, function-wide standards, and coaching of senior peers.
2. Use principal-appropriate verbs: Pioneered, Set, Shaped, Championed, Transformed, Steered. Avoid generic verbs like "helped" and "worked on" — they read as low-ownership.
3. Quantify outcomes: Numbers, percentages, and dollars beat adjectives. "Reduced churn 22%" is more persuasive than "significantly improved retention".
4. Match System Design, Microservices, AWS keywords: These are the ATS-critical terms for Senior Software Engineer roles. Make sure they appear in both your skills section and at least one bullet point.
5. Tailor to the job description: Run your final resume through the ATS checker against the specific JD. Aim for 70%+ keyword match before submitting.
