"As a QA lead, you'll be responsible for creating project roadmaps and directing your team of QA engineers to achieve project goals. In an interview, expect to answer a mix of questions that will evaluate your QA testing skills as well as people management abilities."
Have you had a defect that was found by a customer that should have been caught during the testing phase? If so, how did you handle the escaped defect.
I followed up with the customer and asked how they discovered the defect. I then determined what part of the troubleshooting process we missed that would have revealed the defect to us.
