复试：讲你做过的研究
「这件事里，哪一部分是你自己做的？」
Copy the prompt, then pick a model. It plays the interviewer and asks you through it scene by scene instead of handing you the answer.
On a phone with the app installed, the system opens the app directly. Links cannot open external apps inside WeChat — open it in a browser first.
The copied text ends with the answer key the model grades you against. Don't read it yourself first — working it out on your own is the point.
整场只有一条最重要的纪律：你一说「我们做了」，它就打断你 —— 你做了哪一部分？
第二幕会顺着一个具体的决定往下追：当时有哪几个选项、你为什么选了这个、现在回头看还会不会这么选。说不出一个自己做的决定的人，无论项目多好，这一场都不算过。
还有一问是分水岭：说得出最近读的一篇相关论文，还要说得出它哪里不够好——带着问题读过，和通读过，在这一问上分得很开。

How to use this
The more specific the prompt, the sharper the grading: each specific one carries the root-cause checklist for that kind of situation, and the generic group is the fallback when none of them fits. The system design set grades you on "a benefit with no cost attached means you memorised it"; here the line is different: if you can't give a specific, it's empty.
How to start
- Pick one, open it, copy the prompt.
- Paste it into a brand-new conversation.
- Say in a sentence or two which thing you're going to talk about, then wait for its questions — unlike the system design set, where you say nothing after pasting.

Three traps
- When it starts consoling you, point it back to the "don't praise me" rule — the two retrospectives are the likeliest to summon a model's soothing persona, which turns the whole thing into emotional support rather than a retrospective.
- Cut it off when it tries to complete your answer for you. You say "I don't remember", it offers "probably because the schedule was tight" — and that sentence is no longer your memory.
- Before pasting a CV or a design doc, strip out phone numbers, email addresses and anything your company wouldn't want leaving the building.
Got a proposal to pitch? Start with defending it. Just finished a project or lived through an outage? Do those retrospectives while you still remember. Job hunting? Audit the CV first, then take the lines that survived into the behavioural drill.
