  • A campus report on requestFor the colleges you pick: how active each is on Priors, how its players do in rated contests by rank, its clubs' standing, and the events held there.
  • Aggregated, never personalReports describe a campus, not a person. We never share an individual's data without their consent.

A live room for the interview itself

The candidate and your panel see the same board. Answers stay on your side until you reveal them.

  • Puzzles, with hints on cuePush any of the 100 puzzles. The candidate locks a gut guess with a range, then works it out while you reveal hints one at a time.
  • Real market makingOpen a market on your own contract, trade at the candidate's quote, add new information midway, and settle with P&L for both sides.
  • Your own questionsKeep a question bank with answer keys. The candidate sees only the question; you see the key and whether a number is right.
  • Scorecards without groupthinkEach panel member scores five areas privately and sees the others' only after submitting their own. Scheduling, calendar invites and reminders are built in.
Your panel and the candidate share one room, beside your own video call.

Hard to hand to AI

Built so the score reflects the candidate, not a chatbot or a friend.

  • Seconds, not minutesEach decision has a few seconds on a clock kept by our server. Typing a prompt and reading the reply costs more than the round allows.
  • Pictures, not textScatter plots and charts arrive as images, so there's no data to copy and paste anywhere.
  • Made fresh, kept hiddenRounds are generated on our server as they're played, and answers stay hidden until the round closes. There's nothing to look up beforehand.
  • Flagged for your reviewSuspicious patterns are marked on each candidate's result. You clear or uphold every flag before you decide.

Questions firms ask

What's in a campus report?

How active a college is on Priors, how its players do in rated contests by rank, its clubs' standing, and the contests and sessions held there. The Priors team prepares it for the colleges you pick. It's aggregated: we never share an individual's data without their consent.

Can a contest be open to only some colleges?

Yes. Entry can be limited to verified email addresses at the colleges you choose, on the games and levels you pick, with a live leaderboard.

Do candidates need an account?

No. Each candidate gets their own link by email, or you share one open link on a careers page. They play in any browser, on a laptop or phone, with nothing to install.

How long does a screening round take?

You choose: one to six games of 30 seconds to 3 minutes each, with a short practice before each game that doesn't count. Three or four games take about ten minutes.

Can we use our own interview questions?

Yes. Add them to your question bank with an answer key, then push them in the live room. The candidate sees only the question; you see the key and whether a number is right.

Which video tool do interviews use?

Your own: Zoom, Meet or Teams. Paste the link when you schedule. The Priors room carries the shared work alongside the call.

Do you connect to our applicant tracking system?

Not yet. Results export as CSV, and every candidate's report prints or saves as a PDF.

What does it cost?

Start with a free pilot on a live role. We agree pricing with you afterwards, once you've seen the results.
