Your question is Synchronization in Automated Scripts. 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).
Describe how you handle synchronization issues in automated scripts. Explain how you prevent a script from racing ahead of dynamic application state, and how you handle shared resources when tests run concurrently. Keep the answer practical and mention the tools, wait conditions, or synchronization primitives you would choose.
