What questions should I ask in a job interview?

Candidates without their own questions are rated significantly lower in structured interview studies (OPM Q018) — they signal a lack of interest. Three high-value question categories: (1) About the role: 'What would success in this position look like after 6 months?' (2) About the team: 'How does the team work together — more independently or collaboratively?' (3) About the company: 'What is the biggest challenge this department is currently managing?' Caveat: Questions that could be answered with 60 seconds of Google research ('How large is your company?') signal a lack of preparation. Questions about salary: In the first interview, only if you are asked — otherwise defer the topic to round 2.
