Likely interview questions for this role
Written from this job description, not a generic list. Each one notes what the interviewer is really checking.
Behavioral
Tell me about a time you noticed an artifact in the tracing and had to figure out whether it was equipment or physiological.
real hands-on experience troubleshooting signal quality under time pressure
Tell me about a time a patient was anxious or scared about the sleep study and how you talked them through it.
bedside manner and ability to explain unfamiliar procedures in plain language
Tell me about a shift where equipment malfunctioned partway through a study. What did you do, and what happened to the data?
troubleshooting under pressure and honesty about documenting incomplete or compromised data
Describe a time you had to lift or transfer a patient safely, maybe with help from someone else.
comfort with the physical demands and safe patient handling practices
Technical
Walk me through how you set up a patient for an overnight PSG study, from the moment they arrive to the first calibration check.
whether the candidate actually knows the electrode placement and calibration workflow, not just the terminology
How do you decide when to titrate CPAP versus move to BiPAP or ASV during a study?
depth of clinical judgment around PAP therapy protocols, not just button-pushing
What's the difference in how you'd run an MSLT versus a standard overnight study, and what do you watch for differently?
whether they understand daytime testing protocols beyond basic night studies
How do you fit a PAP mask for someone who's claustrophobic or has facial hair that's making the seal difficult?
practical problem-solving with equipment fit issues that come up constantly
How would your approach differ prepping an older adult with mobility issues versus a younger, more active patient for the same study?
awareness of age-specific care needs called out in the job posting
What does a clean, artifact-free tracing actually look like to you, and how do you keep it that way through the night?
whether they can articulate quality standards rather than just following a checklist
Situational
A patient pulls off several leads in the middle of the night and is agitated about being watched on camera. What do you do?
how they balance patient reassurance with keeping the study technically valid
You're working alone overnight and a patient shows signs of a cardiac event or severe desaturation. Walk me through exactly what you do first.
whether they can prioritize patient safety and know escalation steps without a supervisor present
Since you're not yet registered, how are you planning to work toward RPSGT, RST, or RRT-SDS within three years while working a casual schedule?
genuine commitment to certification versus just checking a box to get hired
A physician asks you a question about sleep medication timing that's outside your scope. How do you handle that in the moment?
understanding of scope of practice boundaries between tech and physician roles
