Your question is Experience With Payment Systems. 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).
Do you have experience with payment systems? If yes, tell me about the most relevant one and what you tested end to end. I’m looking for the type of payments flow, your role, and any issues you caught or helped prevent. Keep it specific and focus on what you owned.
