Hello Dana,
Agree with the comments from David and Lisa, I would also look to understand if the applicant has appropriate training/experience for the organization size, regulatory rigor - Class 1, 2, 3 , PMA/510k, and product type. Often there is nuances that are either insignificant, or pose a large learning curve in applying the QMS within an organization. The BOK for CMDA is a great resource as well as basic QMS and quality project deliverable type questions from CQM-OE, CQE , and CRE BOKs.
If you are looking at the EU, a definite MDR/IVDR question or two is definitely warranted. Also, don't forget the update to risk for ISO14971 -2019 and the guidance ISO24971-2020 and tie ins to the QMS. Good luck with the interviews.
Regards,
George Marcel
