Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
About your past
Tell me about a time you troubleshot an instrument problem on your own. How did you find the cause?
What they are checking: Whether they can fix instrument problems on their own, since a small rural lab rarely has a specialist nearby.
How do you stay on top of competency requirements and skills rosters across different areas of the lab?
What they are checking: Commitment to keeping competencies current across the broad testing a small lab handles.
What would you do
In a small rural lab you may be the only tech on shift. How do you prioritize stat orders, routine work and phlebotomy draws at the same time?
What they are checking: Independent workload management in a small hospital lab where there is no one to hand off to.
A provider calls frustrated that a result is taking too long. How do you handle the call?
What they are checking: Whether they stay professional with impatient providers without cutting corners that would put a wrong result in the chart.
About the work
A potassium result comes back critically high on a patient whose earlier results were normal. What do you check before you call it?
What they are checking: Whether they consider hemolysis and other pre-analytical errors before reporting a result that could change treatment.
Your chemistry analyzer's QC is out on one level. Walk me through what you do next.
What they are checking: Knowledge of QC rules and the discipline not to release patient results until the problem is resolved.
Tell me how you would do a capillary draw on an infant, and what you watch for.
What they are checking: Collection skill across ages, since the role includes phlebotomy and capillary draws.
How do you decide whether a specimen should be rejected and recollected?
What they are checking: Judgment on specimen integrity, which protects patients from results based on bad samples.
What's your experience with point of care testing, and how do you make sure nursing staff run it correctly?
What they are checking: Understanding of POC quality oversight, which labs often share with nursing.
Walk me through a crossmatch or type and screen, and what you'd do if you found an unexpected antibody.
What they are checking: Blood bank knowledge, which carries serious patient safety risk in a small hospital.
