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 your experience with pediatric polysomnography. What do you change for a child?

What they are checking: Whether they can adapt hookup, monitoring and communication for kids and their parents in the lab.

Tell me about a time you were the only tech on shift and something went wrong with equipment. How did you handle it?

What they are checking: Whether they stay resourceful and composed on 12-hour PRN shifts where help may not be close.

What would you do

Halfway through the night a lead starts throwing artifact. What do you do to fix it without waking the patient more than you need to?

What they are checking: Whether they can troubleshoot signals calmly while protecting both data quality and the patient's sleep.

How do you fit a PAP mask for someone who is anxious or claustrophobic about wearing it?

What they are checking: Whether they can coach a nervous patient to comfort, since a poor fit can wreck the titration.

Your patient's oxygen saturation drops sharply and stays low, or you see a dangerous arrhythmia on the ECG channel. What do you do?

What they are checking: Whether they recognize emergencies during a study and follow the center's safety protocol rather than just recording.

A patient tells you at 2 a.m. they want to stop the study and go home. What do you say?

What they are checking: Whether they respect patient choice while explaining the cost of quitting and documenting it properly.

About the work

Walk me through your setup for a routine overnight study, from reviewing the chart to the first calibration.

What they are checking: Whether they follow a reliable, ordered routine so nothing gets missed before lights out on a solo PRN shift.

How do you measure and place electrodes using the 10/20 system, and how do you know your placement is right?

What they are checking: Whether their hookup is precise and repeatable, since bad placement ruins a whole night of data.

Tell me how you run a split-night study. When do you decide to start PAP titration, and how do you move pressures?

What they are checking: Whether they know AASM titration criteria well enough to make sound calls without a physician in the room.

What is different about setting up and running an MSLT or MWT the next day compared with an overnight study?

What they are checking: Whether they understand daytime testing protocols, timing rules and what makes those results valid or invalid.

How do you approach scoring a study? Which AASM rules do you find people most often get wrong?

What they are checking: Whether their scoring and analysis are accurate enough that a physician can trust the report.

What do you document before you leave in the morning so the day team and the reading physician have what they need?

What they are checking: Whether their handoff and documentation are complete, since the physician relies on the tech's notes to interpret events.
