e.g., what’s the volume of the earth’s oceans (in cubic km); or, how many prime numbers contain strictly increasing digits.
It’s a very interactive game and focuses on some ideas that are central to what we do at Jane Street: thinking about hard problems, assessing confidence levels, trying to strike a balance between quick-and-rough estimates versus more refined solutions. You can join the competition as an individual (and we’ll put you in a team), or you can join with friends as a team. There’ll be prizes for the winning team.
The event is free for everyone
