Your question is Testing High-Volume Transaction APIs. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Tell me about a time you had to define the testing strategy for API endpoints handling high-volume transactional data. How did you decide what to test first, how did you align engineers and stakeholders on risk, and what was the outcome?
