The research deep-dive

Walk through "The research deep-dive" in order, then name the proof that tells you it worked.

Step 1 of 2

The deep-dive is where you defend a real project under adversarial questioning. Pick one where you made the key decisions, because the whole round is built to find out whether the choices were yours and whether you understood them.

  1. 1Problem and hypothesis first. Open with the question you were answering and what you believed before you ran anything. Set the stakes in one or two sentences.
  2. 2Method, with the alternatives named. Walk the approach you took and, critically, the ones you rejected and why. Naming rejected alternatives is what separates an owner from a passenger.
  3. 3How you knew it worked. Quantify the result and the eval that proved it. State the metric, the baseline and the variance you had to rule out.
  4. 4The weakest part, volunteered. Close with the limitation you would attack next. Saying it before they find it is the single strongest move in the round.

Expect probing that is adversarial on purpose: “what would you do differently,” “how do you know it wasn't noise,” “what's the weakest part of this.” These are not traps to dodge. They are the test itself.

Truth-seeking is the thing under examination

Cursor screens hard for caring more about what's true than about being right. In the deep-dive that means volunteering a real limitation scores higher than defending a flawed choice. If a reviewer finds a hole you knew about and hid, you fail the value, not just the question.
