Questions to Ask Your Interviewer
"What does success look like in this role after one year?"

The STAR Method for Behavioral Questions
Structure your answers:
- Situation: Set the context
- Task: Describe your responsibility
- Action: Explain what YOU did
- Result: Share the outcome (quantify if possible)
Example:
"Tell me about a time you improved a process."
S: "At my previous company, deployments took 3 hours and required manual steps."
T: "As the senior engineer, I was tasked with improving deployment reliability."
A: "I implemented a CI/CD pipeline using GitHub Actions, added automated testing, and created rollback procedures."
R: "Deployments went from 3 hours to 15 minutes, and we reduced production incidents by 60%."
