> Lead the conversation.

## Drive, check in, adapt

Keep the diagram tidy and labelled, with data flows numbered for key operations. Manage time: do not spend twenty minutes on requirements or dive into one component before the end-to-end design exists. Treat hints as gifts: when the interviewer asks "what if this server fails?", they are pointing at something to address. If you do not know a technology, reason from principles rather than bluffing.

## A tour guide

A good tour guide shows the whole map first, then takes the group to the most interesting places, checking that nobody is lost.

## Summarise at the end

A 30-second recap of requirements, design and key trade-offs leaves a clear final impression.

**Quiz:** What should you do when the interviewer asks "what if this component fails?"

- [ ] Change the subject
- [ ] Say it will not fail
- [x] Treat it as a hint and discuss failure handling for that component
- [ ] Start over with a new design

*Answer:* Treat it as a hint and discuss failure handling for that component. Hints point to what they want to assess.
