D28 模拟面试日：国内/海外各一套全流程，自评

• 一次模拟面试之后，你怎么做一次客观的自我评估，而不是停在「感觉还行」？After a mock interview, how do you assess yourself objectively instead of settling for 'that felt okay'?

  分析过程 · 先想清楚再作答

  1. 这题在考你有没有把练习工程化。答「录下来多听几遍」只是及格线，真正的区分度在于有没有可重复的评分口径和事先定好的阈值——没有口径，两次模拟之间就没法比较，也就谈不上进步。
  2. 客观的前提是有可回放的证据，所以先固定三件事：全程录音或录屏、按时间盒计时、事后对着回放打分而不是结束时凭感觉打。刚讲完的十几分钟里自我评价偏差最大，讲得顺就全盘肯定，卡过一次就全盘否定。
  3. 然后用固定维度代替整体印象：自我介绍、项目讲解深度、编码、系统设计、沟通与反问，各 1 到 5 分，满分 25。关键是每个维度要写好 1 分、3 分、5 分各长什么样的锚点描述，否则同一个「4 分」在两次之间根本不是同一件事。
  4. 阈值要在打分之前定好，这是防止事后给自己找理由的唯一办法：任何单项低于 3 分就进弱项清单，总分低于 18 分就隔两天把整套流程重跑一次，而不是硬着头皮往下走。
  5. 最后一步才是全部价值所在——把低分翻译成四列：现象、根因、最小动作、怎么验证。现象必须是回放里能指着看的事实（带时间、带原话），「讲得不好」不算，「项目讲解到第 8 分钟还没说到我做了什么」才算；最小动作必须一天内做得完；验证必须可观察，最好带数字门槛。
  6. 可以预期的追问：一个人怎么产生追问？用大模型当面试官，但必须先把追问纪律写进指令——一次只问一个问题、基于我的回答连追三层、全程不评价不夸奖不给答案。不写纪律，它会退化成一个不停鼓励你的助手，那就失去了模拟的意义。

  How to reason about it · think before answering

  1. This asks whether you have engineered your practice. 'Record it and listen again' is the passing floor; the discriminator is a repeatable rubric plus thresholds fixed in advance, because without a rubric two sessions are not comparable and improvement is unmeasurable.
  2. Objectivity requires reviewable evidence, so fix three things first: record audio or screen throughout, run the real time boxes, and score against the recording afterwards rather than on feeling at the buzzer. Self-assessment is at its most distorted in the minutes right after you finish.
  3. Then replace overall impression with fixed dimensions: self-introduction, project depth, coding, system design, and communication plus candidate questions, each scored 1 to 5 for a total of 25. What makes it work is writing anchor descriptions for what a 1, a 3, and a 5 look like — otherwise the same '4' means different things in different sessions.
  4. Set thresholds before scoring, which is the only defense against rationalizing afterwards: any dimension below 3 goes on the weakness list, and a total below 18 means rerunning the whole loop two days later instead of pressing on.
  5. The final step carries all the value: translate low scores into four columns — observation, root cause, smallest drill for tomorrow, and how to verify. An observation has to be a fact you can point at in the recording, with a timestamp and the actual words: 'explained it badly' does not qualify, 'eight minutes into the project story and still had not said what I personally did' does. The drill must fit in one day, and verification must be observable, ideally with a numeric bar.
  6. Expect the follow-up: how do you generate follow-up questions alone? Use a model as the interviewer, but write the interrogation rules into the instructions first — one question at a time, three consecutive layers of follow-up grounded in what you just said, and no praise, no evaluation, no supplying the answer. Without those rules it degrades into an encouraging assistant, which defeats the point.

  答题要点

  • 先有证据再有判断：全程录音或录屏、按时间盒计时、事后对着回放打分，不在结束当场凭感觉打
  • 用固定五个维度（自我介绍、项目讲解深度、编码、系统设计、沟通与反问）各 1 到 5 分、满分 25，并给每个维度写 1/3/5 分的锚点描述
  • 阈值先定后打：任何单项低于 3 分进弱项清单，总分低于 18 分隔两天重跑整套流程
  • 把低分翻译成四列：现象、根因、最小动作、怎么验证；现象必须是回放里能指着看的事实，动作必须一天内做得完
  • 一个人练时用大模型当面试官，但要先写死追问纪律：一次一问、连追三层、不评价不夸奖不给答案

  Key points

  • Evidence before judgment: record throughout, run real time boxes, and score against the replay rather than on feeling at the buzzer
  • Use five fixed dimensions (intro, project depth, coding, system design, communication and candidate questions) scored 1 to 5 out of 25, each with anchors for what 1, 3 and 5 look like
  • Fix thresholds before scoring: any dimension below 3 goes on the weakness list, a total below 18 means rerunning the loop two days later
  • Translate low scores into four columns — observation, root cause, smallest drill, verification — where the observation is a pointable fact and the drill fits in one day
  • Practicing alone, use a model as interviewer but write the rules first: one question at a time, three layers of follow-up, no praise, no evaluation, no answers
