About your past
Tell me about a time you had to discipline or let go of an employee. How did you handle it?
What they are checking: Whether they can handle the hard parts of supervision fairly and with documentation, since the posting expects it.
How do you make yourself useful to nurses and physicians who call the lab with questions?

Tell me about a time you hired someone who turned out to be a great fit. What did you look for in the interview?
What they are checking: Whether they have thought about what makes a strong lab hire, since interviewing and hiring are part of the role.
What would you do
Your lab just failed a proficiency testing event on one analyte. What do you do next?
What they are checking: Whether they know how to investigate the root cause, document corrective action and protect patient results in the meantime.
A tech tells you QC was out on a run but they released patient results anyway because the ED was waiting. What do you do?
What they are checking: Whether they put patient safety first, recall results if needed, and coach without creating fear of reporting.
You may oversee more than one lab or department. How would you stay on top of operations at a site you can't be at every day?
What they are checking: Whether they can lead through systems, check-ins and data rather than needing to be in the room.
About the work

What they are checking: Whether they understand the full testing process and know most lab errors start before the sample hits the analyzer.
How do you plan and run a method validation for a new instrument?

What quality indicators would you track in a lab, and what would make you act on one?
What they are checking: Whether they can choose measures like turnaround time, rejection rates and QC failures and use them to improve.
What regulations and accrediting standards have you worked under, and how do you get ready for an inspection?
What they are checking: Whether they know CLIA, CAP or Joint Commission expectations and keep a lab inspection-ready all the time.
