Every question with a source
No question stands there without a basis. Each carries a source quote from the material the recruiter actually has — CV, cover letter, job posting or company profile.
Questions about a job posting and a CV — any chatbot can give you those. But a prompt throws everything into one pot: it asks with everything you know, not with what a recruiter actually has in front of them. JACVault keeps the two sides cleanly apart: every question is built only from the submitted material — CV, cover letter, job posting, public company profile — and carries a source quote. Your full profile, your evaluation and your salary target stay on your side: as coaching — and as strengths you bring up deliberately, because the recruiter doesn’t know them yet.
A real interview is always asymmetric: the two sides know different things about each other. JACVault rebuilds exactly this asymmetry — with two separate spaces that are never mixed. One feeds the questions, the other feeds your answers. And because JACVault built your application itself, that context is already there — on both sides.
Only the submitted material — a recruiter has nothing more. Every question in the dossier is derived solely from it and carries a source with a quote.
Your full context, which the recruiter doesn’t have. From it come coaching hints, your salary strategy and “your advantage” — strengths that aren’t in the material.
At JACVault a question is never just a sentence. You get it broken down: the question itself, the recruiter’s thinking behind it, the evidence with a source quote, a coaching hint for your answer — and the classification of how hard it is and in which round it’s likely to come up.
Every application gets the solid base preparation. Premium adds more questions, all categories and the full coaching.
Both levels follow DACH conventions. Formal or informal address: that follows the company’s culture, not a rule of thumb.
Your preparation comes as two PDFs: the full interview dossier to work through, and the one-page cheatsheet “at a glance” for the last minutes before the conversation.
Download the sample cheatsheet and see for yourself how much fits on one page: focus, key messages, salary range and the most important questions — each with its evidence.
Fictional company and person — for illustrating the structure only
Other tools prompt a language model with the posting and a CV — everything in one pot, nothing grounded. JACVault built your application itself and knows both sides first-hand: the submitted material the questions come from, and your full profile your answers draw on.
No question stands there without a basis. Each carries a source quote from the material the recruiter actually has — CV, cover letter, job posting or company profile.
The questions rest solely on what you submitted — just like in the real conversation. That’s why they hit realistic points: gaps, contradictions, requirements — not everything that exists about you somewhere.
Coaching per question, your salary strategy and “your advantage” — strengths from your full profile that aren’t in the material. Knowledge a one-pot prompt can’t have.
Self-introduction, your own questions as a mandatory phase, salary by DE/AT/CH and the form of address by company culture — prepared by the rules that apply in a German-speaking interview.
Solely from the material a recruiter actually has in front of them when reviewing your application: your optimized CV, your cover letter, the job posting and publicly available company info. Every question carries a source quote from exactly this basis — nothing is invented.
No, and we deliberately don’t promise that. No one can predict real interview questions. JACVault prepares you for the topics most likely to come up from your material and the posting — with evidence for why. That’s thorough preparation, not fortune-telling.
These are strengths from your full profile that don’t appear in the submitted material — so the recruiter doesn’t know them. In the premium depth, JACVault flags them per question, so you can bring them in deliberately where they count most.
Automatically, as soon as your application is finished. You’ll find it right in the cockpit on the relevant application — without triggering anything.
The full journey: how JACVault worksThe dossier is the full write-up: all questions by category with evidence and coaching, self-introduction, your questions, salary coaching and process. The cheatsheet “at a glance” condenses the essentials onto one page — for the last minutes before the conversation.
From the salary target you’ve set. From it comes a concrete strategy: recommended range, timing and the regional conventions for DE, AT or CH. Salary coaching is part of the premium depth.
That follows the company’s culture, not a fixed rule. For German-language interviews, JACVault matches the form of address — formal or informal — to what fits the specific company.
Yes — that’s what the interview simulation is for: a written mock interview in chat against someone who only knows your submitted material, followed by a feedback report.
