Internal audits of an MDQMS at regular intervals keep a medical device-producing company free of worries. It often happens that with time even the most effective quality management processes retain the same vigor. This causes loopholes in the manufacturing operations that ultimately affect the end product’s quality. So, keeping track of every action through documentation and checking them with the actual performance at a given time, is necessary. This is where the role of an ISO 13485 Lead Auditor Certification comes to play. Medical device producers hire individuals possessing this certification. They demand performance-recording documents from MDQMS to analyze and detect flaws. For this purpose, they schedule individual sessions and inform the participants. Certified professionals are empowered to conduct audits because they have in-depth knowledge of ISO principles. The same knowledge must be exhibited while answering the questions of an interviewer. Here is an idea of the type of questions one might face while getting shortlisted for a lead implementer position. Practicing beforehand is essential for interviewees to avoid a lack of confidence and showcase their expertise brilliantly.
