Opportunity brief
See the pattern. Price the odds. Beat the clock.
Priors Weekly Contest #1 is a short, rated online contest in the skills trading firms test in interviews: reading data at a glance and pricing uncertainty under time pressure. Everyone plays exactly the same rounds at the same time, and your place earns you a contest rating, much like a Codeforces round.
How it works:
- Stage 1: Guess the correlation (60 seconds). Scatter plots appear one after another. Call each one's correlation before the clock runs out.
- Stage 2: Make a market (90 seconds). Quote a bid and an ask on dice, coin and card contracts. Get the fair value inside your spread, and keep it tight.
- The stages run back to back, about 3 minutes in total.
- Answers stay hidden until the contest closes. Then you see the full leaderboard, the podium, your own answers next to the truth, and your rating.
When: Saturday, 31 October 2026, 7:00 PM IST. Entry is open for the first 5 minutes only, so be on time.
Eligibility: Open to everyone: students from any college or year, and working professionals. Guests can play, but sign in (email, Google or GitHub) to get a rating. A contest is rated once at least 5 signed-in players take part.
How to take part:
- Before Saturday, warm up on the two games at priorslab.com. It's free, with no sign-up needed to practise.
- Join at 7:00 PM IST on Saturday.
Why play:
- Practice that feels like a trading interview, under a real clock.
- A rating and a rank (Rookie to Grandmaster) that grows with every weekly contest.
- A round-by-round review of your answers against the truth.
Rewards: Contest rating and a spot on the public leaderboard.
