背调公司做的第一件事，是把你的履历摊成一条时间线，然后看四样东西：**有没有重叠、有没有空档、每段待了多久、写的年限和算出来的对不对得上**。这四样全是能算的——所以这里由代码算，一个数字都不经过模型。 贴进时间线，代码会标出所有两个月以上的空档（背调表按月填，空的格子自己会说话）、所有时间重叠（这是最先炸的一项：核实方同时向两家发函，两边在职证明一对就摆在桌面上）、每段的实际时长和不足一年的段数，并把你简历上写的总年限与时间线算出来的实际跨度对一遍——**多报了几个月，HR 拿计算器就能算出来，而且他们真的会算**。 然后模型接手它擅长的部分：每一处会被追问什么、空档口径怎么说才一句话说完、多段短期怎么给一个统一的解释、以及已经发现的不一致该怎么补救。 有一句话值得先说：**offer 前自己发现写错，代价是尴尬；背调阶段被发现，多数公司直接撤 offer，而且不解释。** 这个工具的全部价值就在这个时间差里。$3 解锁逐项风险与追问预案、与前东家的口径对齐建议、以及不一致的补救话术。The first thing a background-check firm does is flatten your history into a timeline and look at four things: **overlaps, gaps, tenure, and whether the years you claim match the dates you gave**. All four are computable, so here they're computed — no number passes through a model. Paste the timeline and the code flags every gap of two months or more (these forms are filled in by month; the empty cells speak for themselves), every overlap (the thing that blows up first — both employers get letters, and the two confirmations sit side by side), the real duration of each role, how many ran under a year, and whether the total you claim survives arithmetic. **Overstate by a few months and HR finds it with a calculator — and they do use one.** Then the model handles what it's good at: what each item invites as a follow-up, how to state a gap in one sentence, how to give several short stints one coherent explanation, and how to repair an inconsistency you've already found. One thing worth saying up front: **finding your own mistake before the offer costs you some embarrassment; having it found during the check usually costs the offer, without explanation.** That time difference is the whole value here. $3 unlocks per-item risk and follow-up prep, how to align your account with former employers, and repair scripts.
逐项风险与可能被追问的问题、空档与离职原因的成文口径、与前东家说法对齐的自查清单（社保／个税／离职证明三处最容易对不上）、以及已经发现的不一致该怎么补救、什么时候该主动说。Per-item risk and the follow-ups each invites, written accounts for gaps and departures, a checklist for aligning with former employers (the three records that most often disagree), and how — and when — to volunteer an inconsistency you've already found.
本工具只对你填写的日期做算术与一致性检查，不查询任何数据库、不联系任何雇主、也不代表任何背调公司的实际口径——不同公司、不同岗位、不同国家核查的深度差别很大。「两个月以上算空档」「不足一年算短期」是本工具的粗口径，不是行业标准。请勿用本工具润色不真实的经历：本工具的用途是**发现并改正自己简历上的错误**，不是帮助掩盖。伪造工作经历在多数国家可构成欺诈，被发现通常导致撤销录用或解除劳动合同，且不受既往表现保护。你填写的内容不入库；如需保守起见，公司名可用「某某科技」代替，计算只用日期。This performs arithmetic and consistency checks on dates you type. It queries no database, contacts no employer, and represents no screening firm's actual practice — depth varies widely by company, role and country. "Two months is a gap" and "under a year is short" are this tool's conventions, not standards. Do not use this to polish a history that isn't true: the purpose is to **find and fix your own errors**, not to conceal. Misrepresenting employment can constitute fraud in many jurisdictions and typically results in a withdrawn offer or termination regardless of performance. Nothing you enter is stored; you can replace company names with placeholders — only the dates matter to the computation.
