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 project where you took an idea from a notebook prototype to something other people relied on.
What they are checking: Whether they have carried work past exploration into code that is tested, readable and reusable.
Tell me about a time a result looked too good. What did you check?
What they are checking: Whether they have the instinct to suspect leakage, bias or bugs before celebrating a strong number.
What would you do
Your algorithm agrees with the lab sleep study on most patients but misses badly on a small group. How do you figure out why?
What they are checking: Whether they dig into subgroups and failure cases instead of being satisfied with a good average.
A senior engineer suggests an approach you think won't work on real patient data. How do you raise it?
What they are checking: Whether a junior engineer can disagree with evidence and respect instead of staying quiet or pushing too hard.
The role is hybrid in Caesarea. How do you keep collaborators informed when you're working through a hard analysis on your own?
What they are checking: Whether they share progress and blockers early so teammates are not surprised by late findings.
About the work
WatchPAT works from proprietary signals collected at home overnight. What signal processing work have you done on noisy physiological data?
What they are checking: Whether they have practical experience cleaning and analyzing real biosignals rather than only textbook examples.
How would you approach detecting a breathing event from a peripheral signal like pulse or oxygen saturation when there's motion artifact?
What they are checking: Whether they can reason through filtering, feature extraction and artifact handling for a sleep study signal.
What metrics would you use to judge a sleep apnea detection algorithm, and why might accuracy alone be misleading?
What they are checking: Whether they understand sensitivity, specificity and agreement with a reference standard in a diagnostic setting.
This is an FDA-cleared device. How does working on a regulated medical product change how you write and document algorithm code?
What they are checking: Whether they grasp that traceability, validation and controlled changes matter as much as a clever result.
Which tools and languages do you use for analysis work, and what would you reach for first on a new data set?
What they are checking: Whether their working tools fit a signal and algorithm team, and how they start on unfamiliar data.
