About
Get job-ready. Hire with confidence.
Quark9 is a career preparation and candidate assessment platform for students, freshers, job seekers, and interviewers. Candidates check their resume's ATS score, practice interviews, and take assessments to understand where they stand - while recruiters use that same signal to compare candidates and shortlist faster.
Candidates first
Every product decision starts with the candidate. Faster feedback, fairer scoring, no ghosting. We measure ourselves by post-interview NPS, not seat count.
Bias is a bug
We publish our scoring rubrics. Recruiters can audit every number. Every candidate gets evaluated against the same criteria - that's the whole point of building this.
AI augments, never replaces
A recruiter still makes the final call. Quark9 surfaces signal, ranks the shortlist, and explains its reasoning. Humans decide who joins the team.

What Quark9 does
For candidates
Students, freshers and job seekers build one profile, then practice and apply from it. Applying, the real interview rounds companies run (AI, coding and aptitude), the ATS score, the resume builder and downloadable interview reports are free. Extra practice rounds are optional and billed per minute.
For hiring teams
Companies screen resumes with AI, run AI interviews and proctored coding and aptitude rounds (with a problem bank of 2,700+ questions), and review scorecards before a recruiter decides. Quark9 connects to Greenhouse, Lever, Workday and BambooHR, with Zapier, webhooks and an API for everything else.
