1.Tell us about a time your work directly changed a number — revenue, cost, time, error rate, satisfaction. What was it before, what did you do, and what was it after?

2.What's something you built, fixed, or improved that outlived your involvement — still running or still used after you moved on?

3.Describe a moment someone above you had to make a call because of what you found or flagged. What happened?

4.Tell us about a decision that didn't work out. What did you miss, and what do you do differently now because of it?

5.What's a time you were wrong about something you were confident in — and how did you find out?

6.Describe a project or role that ended badly (layoff, cancellation, failure). What's the honest read on what led there, separate from things outside your control?

7.What's something you're good at that most people in your field aren't — the thing colleagues come to you for specifically?

8.Walk us through the hardest technical or judgment problem you've solved. What made it hard, and what was the actual insight that cracked it?

9.What's a skill you built the hard way — through repetition or failure — rather than being naturally good at it?

10.Tell us about a time you had to get people who disagreed with you (or each other) to move in the same direction.

11.Describe someone you mentored, unblocked, or made better at their job just by working near you.

12.What's a time you had to deliver bad news or push back on someone with more authority than you?

13.Tell us about a time you had incomplete information and had to act anyway. How did you decide, and were you right?

14.What's something you do differently now at a larger scale (more people, more risk, more money) than when you started?

15.What kind of problem makes you lose track of time? And what kind of work drains you even when you're good at it?
