You face AI interviewers on the way in — and at the best companies you're scored on how well you build with AI once you're there. Practice both. Bring your own key.
* Meta, Canva and CodeSignal already run AI-allowed interviews; HireVue screens millions before a human ever looks. Your first resume analysis runs on our key — free, no signup. Everything after runs on yours, so there's no subscription to trap you.
A real task, a real copilot, and an adversarial interviewer scoring how you direct, verify, and integrate AI output. Nobody else trains this.
Paste a job URL — we pull the posting straight from the employer's ATS API, score the match against your resume, and put a ticket on the rail. Glance, don't read.
Suggestions you accept or reject one at a time — red strike, green replacement, never a rewritten blob. Exports ATS-safe PDF.
Kanban of every application. Detects the employer's ATS from the URL and tells you which machine reads your resume first.
Role archetype → skill tags you control → quizzes that rate you per topic. Priorities ordered by seniority, because order is the advice.
Work a real task with a copilot while an adversarial AI scores your direction, verification, and integration. Hard mode reasons deeply.
Behavioral, system design, coding — calibrated to your prep ratings and the company tier you're walking into.
Server-signed badges on a live page. Scores change, badges revoke — a screenshot can't fake it, and a click lands here.
This category is notorious for billing traps. We charge for exactly two things; everything else runs on API keys you already own.
Paste your Anthropic or OpenAI key. Envelope-encrypted, never shown again.
No keys, no setup — we supply the models.
Real-time voice against an adversarial interviewer. Priced per session because reasoning models cost real money.
