I also understand the importance of following best practices when creating test plans and procedures, so I always make sure my team members are aware of these guidelines. For example, we use the ‘three strikes’ rule to ensure that our test cases cover all possible outcomes.”
Do you have experience working with confidential company information?
The interviewer may ask this question to determine how you handle confidential information. Use your answer to show that you can keep company secrets and ensure they’re not shared with unauthorized individuals.
Example: “I have worked on projects where I had access to sensitive client information, including financial data and private customer details. In my experience, it’s important to maintain confidentiality when working with clients’ information because it could be damaging if it were to get into the wrong hands. To prevent this from happening, I always make sure to store all of my work in a secure location and never leave my computer unattended. I also avoid sharing any confidential information over public channels like email.”
When testing a product, do you prefer to start with the most complex features or the basic ones?
This question can help the interviewer understand how you approach your work and what your thought process is. Your answer should show that you are organized, detail-oriented and able to prioritize tasks effectively.
Example: “I prefer starting with the basic features of a product because it allows me to see if there are any bugs or issues right away.
