Behavioral
Tell me about a time a patient was anxious or claustrophobic about wearing a CPAP mask. How did you handle it?
patient communication skills and ability to de-escalate anxiety without disrupting the exam
Tell me about a time you had to respond quickly to a patient safety issue during a study, like a desaturation or a fall risk.
real experience recognizing and acting on safety events, not just textbook knowledge
How would you explain to a patient, in plain language, what their sleep study is actually going to measure and why it matters?
patient education skills and comfort translating clinical procedure into something a nervous patient can understand
Tell me about a time equipment failed or malfunctioned mid-study. What did you do, and how did you document it?
problem-solving under pressure plus discipline around documentation and escalation
Overnight shifts, night differential, working 7:30pm to 6am — how do you manage your own alertness and stay sharp for scoring and observation late into the shift?
self-awareness about fatigue management, which directly affects data quality and patient safety on this schedule
Technical
Walk me through how you set up a patient for an overnight sleep study, from the moment they arrive to lights out.
whether the candidate actually knows the full electrode and sensor application workflow, not just pieces of it
How do you calibrate your equipment before a study, and what are you checking for during biocalibration?
hands-on familiarity with pre-study checks that catch bad signals before they waste a night of data
What's your process for a CPAP or BiPAP titration, and how do you decide when to change pressure settings during the night?
clinical judgment around titration protocols, since this is a core part of the job
Can you explain what you're watching for during a split-night study versus a standard diagnostic study?
depth of protocol knowledge across different study types the lab actually runs
Have you done MSLT or MWT testing before? Walk me through how the day testing differs from the overnight setup.

Situational
Say you're mid-study and you notice the EEG channels are full of artifact. What do you do in the moment, and what do you try first?
troubleshooting instinct under time pressure without waking or alarming the patient unnecessarily
You're the only tech on overnight shift and you have more than one patient running at once. How do you keep track of both and know when something needs your attention?
ability to manage solo overnight workload and prioritize across simultaneous patients
This role covers five different sleep center locations across the South Region. How do you feel about driving between sites and adjusting to different setups or teams?
flexibility and reliability for a per diem role that isn't tied to one location
