Hash Code is open to university students and industry professionals in Europe, the Middle East and Africa. Participants compete in teams of two to four. Registration is free of charge and will close on 26th February 2018 at 17:00 EET. Your team will be tasked with solving a challenge created by Google engineers using your own computer and programming language and tools of your choice. For this round, your team can compete from wherever you’d like, including from one of our Hash Code hubs. Top scoring teams from the Online Qualification Round will be invited to the Final Round at Google Dublin. We’ll present a second challenge, and the winning teams will be awarded Google prizes.
