How Do You Handle Unexpected Testing Results?
Hiring managers want to know your process for managing surprises during validation. Demonstrate your systematic problem-solving approach.
Possible Answer: When unexpected results arise during testing, I take a methodical approach to resolve the situation properly. First, I re-validate the test to rule out errors. Next, I document the irregular result and notify appropriate internal partners. From there, I research the system components and parameters associated with the result to isolate variables. If the root cause remains unclear, I expand testing to gather more data points and identify patterns. I then summarize my findings in a report with recommendations to address the issue. Explaining unclear testing scenarios requires patience and persistence.
How Do You Prioritize Your Work When Managing Multiple Projects?
Since validation engineers juggle various testing projects, this question tests your time management skills. Showcase your ability to focus on top priorities.
Possible Answer: When managing multiple validation projects, I use a combination of techniques to prioritize the highest value work. I maintain a schedule with key milestones and deadlines for each project to track timing. I touch base with project managers regularly to get input on upcoming priorities based on business needs. By balancing deadline urgency and business criticality, I define the priority order and focus my energy accordingly. I also reevaluate priorities as new projects and tasks emerge. Communication, organization and adaptability allow me to stay laser-focused on the top priorities as changes occur.
Describe Your Experience Validating Software for Regulated Industries.
For regulated sectors like aerospace and medical devices, specialized knowledge is required. Tailor your answer to the specific industry mentioned.
Possible Answer: I will do great in this manufacturing job because I have experience checking software systems for FDA and FAA compliance. I know a lot about 21 CFR Part 11 and what it says about electronic records and signatures. I checked that e-systems used in clinical trials followed the rules for Good Clinical Practice at my last job. I also have experience ensuring aviation software meets DO-178C standards through requirements-based testing. With strong validation skills and knowledge of compliance, I can make sure the product meets quality and regulatory standards.
How Do You Determine When a System Is Ready for Release?
This behavioral question allows you to explain your release readiness process. Showcase your quality focus.
Possible Answer: I use a methodical process to determine a system’s readiness for release into production. First, I check that all items on the master validation protocol have been executed, reviewed and closed. This ensures completion of system, integration and regression testing. Next, I verify successful re-testing of any defects that were identified and resolved. From there, I examine the severity of any open defects based on risk analysis. Finally, I assess if the software meets all defined requirements and business needs for the release. With these validations completed, I have confidence the system is truly ready for go-live with minimal remaining defects. Throughout the process, I communicate closely with stakeholders to align on release readiness.
Discuss Your Experience with Automated Testing Tools.
This question gauges your knowledge of testing tooling and process automation. Tailor your answer to the specific tools listed in the job description.
Possible Answer: I have intermediate experience working with TestComplete to automate validation processes for web and mobile applications. At my last role, I programmed automated UI tests to execute complete test scenarios at scale. By parameterizing inputs across thousands of iterations, we efficiently validated a complex system. I also have exposure using Selenium to automate API testing. My automated testing improved coverage and enabled the validation team to focus manual testing on the trickiest user paths. I am excited to leverage my automation knowledge in this role and expand my skills with your team’s tools and processes.
How Do You Stay Current on Validation Standards and Industry Trends?
Hiring managers want validation engineers who proactively expand their knowledge. Share resources and habits that showcase your continuous learning.
Possible Answer: I recognize the importance of constantly developing my validation skills given how regulations and technologies frequently evolve. I stay up-to-date by reading industry publications like the Journal of Validation Technology and Journal of GXP Compliance. I also attend conferences like the ISPE Annual Meeting when possible. Within my company, I participate in internal training on validation techniques and regulatory updates.
