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
Describe a time you had to make a real-time therapeutic intervention during a titration, like adjusting CPAP or BiPAP pressure. What made you decide to act?
clinical judgment and comfort making independent decisions during overnight shifts
Tell me about a time you trained or mentored a newer tech or student. What did you focus on?
readiness to serve as a preceptor and resource, which the posting explicitly requires
You're working overnight largely on your own. Describe a situation where a patient's safety was at risk and how you handled it.
independent judgment and safety prioritization given minimal on-site backup during night shifts
Tell me about a time a physician or patient pushed back on something you explained about sleep medicine. How did you handle that conversation?
communication skill and confidence educating both clinical and non-clinical audiences
Technical
Walk me through how you'd hook up a patient for a full PSG study, from electrode placement to the moment you start recording baseline data.
whether the candidate has hands-on, current competence with the actual setup workflow, not just textbook knowledge
How do you approach scoring sleep stages and clinical events to stay within the AASM 80% proficiency standard for interscore reliability?
whether the candidate understands and actively manages scoring accuracy, since this is a hard credentialing requirement for the role
Have you run AVAPS or ASV titrations, or MSLT and MWT studies? Tell me about your experience with those and where you feel less confident.
actual breadth of experience with the specific advanced protocols listed in the job, and honesty about gaps
How do you handle setting up and scoring home sleep tests differently from in-lab studies?
whether the candidate understands the distinct equipment and scoring considerations for HSAT versus in-lab PSG
Walk me through how you'd care for a pediatric patient differently than an adult during a sleep study.
whether the candidate can actually apply age-specific care principles the posting calls out, not just recite them
Situational
Tell me about a night where you were mid-study and started seeing a lot of artifact in the tracing. What did you do?
practical troubleshooting skill and whether the candidate protects data quality without disrupting the patient unnecessarily
A patient is anxious and doesn't understand why they need a PAP mask fitting. How do you talk them through it?
patient education and de-escalation skills, since this role requires calming and informing patients overnight with no other staff support
If you noticed a piece of equipment wasn't calibrating correctly right before a patient's study was set to begin, what would you do?
whether the candidate can triage equipment issues fast enough to protect patient scheduling and data integrity
This role rotates across four site locations. How do you handle adjusting to different teams, equipment setups, or routines from one site to another?
adaptability and consistency of technique across varied environments, since the job requires working between multiple sleep centers
