Your question is Design an ATM System. 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 how you would design an ATM system and its add-on features.
Clarify the core ATM operations and the add-on capabilities you would support, then describe the end-to-end architecture. Explain where machine learning is appropriate, how models would be trained and served, and how the system remains secure and available when connectivity or models fail.
Address data, latency, monitoring, evaluation, and operational failure modes.
