Tuenti Challenge 8

You are here

Do you love solving problems? Are you a great coder? Want to compete with the best? The Tuenti Challenge is for you! Registration is already open, so hurry up and sign up now!

It's a contest that consists of some typical programming challenges, and other challenges that don’t include any hints and can be quite tricky, so you’ll really have to give your brain a workout! You can choose the programming language or technique you prefer for each challenge. And remember that it’s not a speed competition, so the quality of your solutions, code, and algorithms really matter!


  • Registration: from March 12th, 2018, to May 2nd, 2018
  • 1st Phase: from April 25th to May 2nd, 2018
  • 2nd Phase: May 25th, 2018

The contest is divided into two phases: the first one will take place online and the second one in our office. The winners of the first phase will be those with the top 30 scores. The score will be computed by taking into account the number of challenges solved and, if there is a tie, the time taken to submit the solution. Some challenges will have a small and a large input, and both will be considered when calculating the score.

The 2nd phase will take place in our Madrid office. They will be invited to a get-together where they will meet our engineers, spend a day working with them, participate in cool workshops and learn how we develop our various products while seeing how we work at Tuenti. Those 10 winners will also receive:

  • 1st Prize: OnePlus 5T (or better) and a certificate
  • 2nd Prize: Nintendo Switch + The Legend Of Zelda and a certificate
  • 3rd Prize: Sphero R2-D2 Droid and a certificate
  • Other finalists: 50€ Amazon voucher and a certificate
