Round 2 of the 2021 Facebook Hacker Cup is less than 48 hours away!

The round will begin on September 25th, 2021 at 10am PDT and will last for 3 hours. The contest can be found here.

You're eligible to compete in Round 2 if you scored at least 24 points in Round 1.

The top 2000 competitors who solve at least one problem in this round will receive a Facebook Hacker Cup t-shirt! We'll begin shipping out t-shirts by early 2022 or earlier, at which point the winners will receive emails with tracking information.

Furthermore, the top 500 competitors will advance to Round 3, taking place on Oct. 9th. Please note that all submission judgments will only be revealed after the round end, and that time penalty will be used to break score ties. More details about rules and other information can be found in the FAQ.

We wish you the best of luck, and hope that you enjoy the contest!
