Quality assurance (QA) specialists can help healthcare industries maintain the quality and performance of software products, such as imaging software or electronic patient records.

During interviews for QA or software testing positions, employers may ask questions to evaluate your technical skills and determine your knowledge of QA processes for healthcare software. Software testing job seekers in the healthcare industry may want to know some questions that may be asked in interviews and how they can answer them effectively.

Whether you are preparing for an interview for a hospital IT team, a health-tech startup, or a medical device company, this article covers important interview questions you’re likely to face in 2026, along with guidance on how to answer them.

Health Care Domain Software Testing Interview Questions

1. What makes software testing in the healthcare domain different from other domains?

Answer: To answer this question, highlight the following:

• Patient Safety and Criticality: A defect can not only annoy a user but also harm a patient.
• Regulatory and Compliance Requirements: Standards such as HIPAA, GDPR (for EU data), and FDA regulations, among others.
• Data Sensitivity: Protected Health Information (PHI) and its strict privacy rules are central to the healthcare domain. They should be protected, and their access is regulated.
• Interoperability: Integration with EHR/EMR, labs, pharmacies, and insurance (payer) systems.
• Traceability and Documentation: Every requirement and test must be documented and traceable.

2. What is PHI, and how does it impact your testing approach?

Answer: PHI (Protected Health Information) is any information in a medical record that can be used to identify an individual, and which was created, used, or disclosed in the course of providing healthcare services. The presence of PHI fundamentally changes the software testing approach, primarily due to the strict legal requirements of HIPAA, which aim to ensure the confidentiality and security of patient data.

Testing approach in case of PHI should focus on:

• Using masked or synthetic data in non-production environments.
• Secure handling of test data, no screenshots of live PHI, no exporting to personal devices.
• Ensuring logging and monitoring don’t expose PHI.
• Access control tests (least privilege, role-based access).

3. Can you explain HIPAA and its implications for QA/testing?

Answer: The Health Insurance Portability and Accountability Act (HIPAA) is a U.S. federal law that establishes national standards to protect sensitive PHI from unauthorized disclosure or access. Its core purpose is to ensure the confidentiality, integrity, and availability of electronic PHI (ePHI) as healthcare transitions to digital formats.

As a tester, your responsibilities include:

• Verifying access controls (who can see what).
• Testing encryption in transit and at rest.
• Checking audit logs for sensitive activities.
• Ensuring session timeouts, password policies, and multi-factor authentication work as expected.
• Confirming that export/print/download functions respect privacy rules and are logged.

4. What is an EHR/EMR, and what do you test in such systems?

Answer: EMR (Electronic Medical Record) is a digital version of the patient’s chart within a single practice. An EHR (Electronic Health Record) is a longitudinal record that spans multiple providers and organizations.

Key test areas for EMR and EHR include:

• Patient registration & demographic details.
• Clinical workflows encompass orders, prescriptions, clinical notes, and laboratory results.
• Interoperability with labs, pharmacies, and imaging systems.
• Performance during peak loads (e.g., morning rounds, OPD hours).
• Data integrity and audit trails.

5. How do you test healthcare interoperability standards like HL7 and FHIR?

Answer: Testing healthcare interoperability standards, such as HL7 and FHIR, involves validating data structure, transmission, and security using both automated tools and manual checks.

Key steps to be followed as a tester:

• Validate message structure and fields against the standard (segments like PID, ORC, OBX in HL7).
• Test API functionality with GET, POST, and DELETE methods, ensuring that correct security measures, such as OAuth 2.0 and HIPAA compliance, are in place.
• For FHIR, validate JSON/XML payloads, as well as resources (E.g., Patient, Observation, Encounter).
• Check conformance profiles and required vs optional fields.
• Test error handling: invalid codes, missing fields, mismatched IDs.
• Test end-to-end flows: e.g., lab order placed → message sent → lab system → result returned → displayed correctly in EHR.

6. How do you approach testing of healthcare workflows end-to-end?

Answer: To approach end-to-end testing of healthcare workflows, prioritize critical workflows, utilize synthetic data to maintain patient privacy, and combine automated and manual testing methods. Develop a comprehensive test plan that includes detailed test cases with preconditions, defines realistic scenarios using synthetic data, and ensures the test environment mirrors production. Focus on compliance, patient safety, and system integrations, and include testing for usability, real-time data processing, and the accuracy of algorithms.

Basic steps to follow are:

• Design end-to-end workflow test cases across multiple systems.
• Validate data consistency between systems (patient IDs, visit IDs, results).
• Include negative and exception paths (canceled orders, rescheduled visits, rejection of claims).
• Utilize traceability to map each workflow step to its corresponding requirements.

In the end, give a concrete example, e.g., “patient visit” workflow:

• Patient registration/appointment scheduling.
• Check-in & triage.
• Provider consultation and order entry (including lab, imaging, and medication).
• Results (lab, imaging) coming in.
• Billing & insurance claims (if applicable).

7. What types of testing are especially critical in the healthcare domain?

Answer: The following types of testing are critical in the healthcare domain:

• Functional testing is necessary to verify core workflows and clinical accuracy from a system perspective.
• Integration and interoperability testing to test the integration of various systems.

• Performance and scalability testing for telehealth and nationwide systems.
• Usability testing for clinicians is often conducted under time pressure; therefore, the UI must be intuitive and straightforward.
• Compliance testing is required to ensure features align with HIPAA, FDA, and local regulations.
• Data migration and data quality testing are essential when moving from legacy systems.

8. How do you test security and privacy in a healthcare application?

Answer: While testing security and privacy in a healthcare application, you should test the following:

• Role-based access control tests (doctor vs. nurse vs. admin vs. billing).
• Verify that users only see patients they’re allowed to see (break-glass scenarios if relevant).
• Test encryption (TLS), secure cookies, and no PHI in URLs or query strings.
• Check logging to ensure that sensitive actions are logged, but logs do not include raw PHI unnecessarily.
• Test session management for timeout, re-login, and concurrency rules.
• Validate data export/download features include only the minimal necessary PHI and encryption where needed.

9. How would you test an e-prescription (eRx) module?

Answer: To test an e-prescription (eRx) module, focus on functional testing of e-prescription workflows, including creating, sending, and canceling prescriptions, and validating compliance with industry standards such as NCPDP SCRIPT. Testing also requires verifying security features, such as authentication and audit logs, and testing integration with other systems like pharmacies and EHRs.

Additionally, confirm the accuracy of clinical decision support (CDS) features, such as drug-drug and allergy alerts, and validate the overall user experience for both prescribers and patients. Also test both clinical safety (alerts) and compliance (e.g., for controlled substances – 2-factor auth, additional approvals).

10. What are validation and verification in healthcare software, and how do they differ?

Answer:

• Verification in healthcare software answers the question, “Are we building the product right?” It ensures implementation meets specifications (reviews, inspections, functional tests).
• Validation answers the question, “Are we building the right product?”It ensures the system meets clinical needs and regulatory expectations (UAT, clinical validation, real-world workflow tests).
• In highly regulated environments (like FDA-regulated devices), both are required with detailed documentation.

11. How do you test a medical device that has embedded software plus a companion mobile app?
