Design-prompt drills

For each case in "Design-prompt drills", name the signal and the response you would use.

Step 1 of 3

Open-ended design prompts are where the onsite and the deep-dive overlap. There's no answer key; they're watching how you decompose an ambiguous problem, where you put the risk and whether you anticipate the failure modes before they bite. Drill these four until you can structure a strong answer in two minutes.

The structure that works for all four

The structure that works for all four

  1. 1Restate and scope. Pin down what “good” means and what you're explicitly not solving. Ambiguity is the test; naming your assumptions is the answer.
  2. 2Propose the design. Sketch the concrete pipeline - data in, signal out - at a level you could start building.
  3. 3Attack your own design. Name the failure mode (reward hacking, contamination, off-policy bias) before they do and the mitigation for each.
  4. 4Define success. State the metric and the validation that would tell you it worked, including how you'd separate real gains from noise.
