Q&A is where I learn the most as an evaluator, because a team's answers reveal what the demo hid. Teams that prepare for these questions look like engineers; teams that improvise look like they got lucky. Prepare all fifteen; you will be asked five.
About the demo
Which part of what we just saw is real, and which is mocked? Answer precisely. Judges reward honesty and punish discovered mocks.
Can you try it with this input? Say yes. If it fails, explain why technically.
What happens when the external API is down or slow? Strong: a fallback or a clear error. Weak: "it wouldn't be".
