Hash Code Programming Contest Runs Again

It's time to get ready for Hash Code 2020, Google's team programming competition in which participants solve Google-inspired engineering problems. This is the seventh edition of contest and the second time it has been open on a global scale.


Hash Code is a competition in which both students and professionals at all skill levels tackle engineering problems set by Google. Participants compete in teams of two to four people and can use the programming languages of their choice.


The contest has two rounds. The first is an Online Qualification Round, taking place this year on February 20th. For this teams can compete from wherever they want, including from one of  Google's Hash Code hubs organized at offices, universities, and cities around the world.

Between 30 and 50 of the top teams from the qualification round (up to a limit of 150 individuals) will be invited to participate in Hash Code Final Round, scheduled to be held on Saturday, April 25, 2020 at the Google offices in Dublin, Ireland. 

Last year, having gone global for the first time, over 70,000 developers registered to take part and 41 teams went to Dublin, courtesy of Google, to compete for prizes.

If you are planning to participate in Hash Code for the first time, getting familiar with past problems is the best way to prepare and the Hashcode Archive has the challenges for both the qualification rounds and finals of the past contests. 

As Lindsay Taub, the Hash Code Program Manager, explains on the Google blog there is never a "right answer" to a Hash Code problem:

Teams spend the entirety of each round working on one challenge, continuously trying to improve their solution. In computer science, this is referred to as an optimization problem, and it’s similar to problems you’d encounter working as an engineer at Google. Also, here’s one pro tip: Your team should submit early and often during the competition so you can test your solutions and keep improving them.

Registration is already open and all you need is Google account to proceed.
