Welcome to your interview.
The question is on your right: Documenting an Unfamiliar Technology. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Tell me about a time you had to create documentation for a technology you were initially unfamiliar with. How did you get up to speed, validate that your guide was accurate for the target audience, and what was the outcome?
