Your question is Building Docs From Zero. 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 a time you had to create technical documentation from scratch for a complex product or workflow with incomplete information. How did you figure out what to document first, align with stakeholders, and make sure the final documentation was actually useful to the people who needed it?
