Welcome to your interview.
The question is on your right: Functional, Regression, and Acceptance. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
What testing methodologies have you used, such as functional, regression, and acceptance testing, in your Citizens work?
