Your question is Learn New Platform Under Deadline. 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).
You are assigned to a project that depends on a complex technology you have not worked with before. You still need to contribute quickly, build enough understanding to make sound decisions, and keep delivery moving without creating avoidable risk.
Give an example of a time you had to learn a complex new technology very quickly. How did you get up to speed, manage stakeholders while you were learning, and make sure delivery stayed on track?
