The final event consisted of several phases, beginning with an informal dinner on Thursday where the finalists were introduced to our team and company culture. Today the 15 candidates participated in several workshops created by some of our most experienced engineers:

  • "Introduction to Development in Tuenti: From the idea to the Web", about the development process of any new feature - by Luis Peralta, Tech Lead.
  • "Honey, I Shrunk the Tuenti", explaining the process of planning, organization, and testing of mobile applications - by Miguel Lara, Mobile Tech Lead.
  • "Frontend Tuenti Internals", describing the evolution of Tuenti’s Frontend from the creation of Tuenti until today - by Diego Munoz, Senior Frontend Engineer.
  • "Web Scalability", about the Tuenti Backend Framework - by Guillermo Perez, Lead Backend Engineer, and Goran Petrovic, Backend Engineer.

After the talks the finalists were interviewed by some of our engineers and HR representatives, before ending the day with an awards presentation ceremony during Tuenti’s classic Friday “Q&A” session.

The event was also attended by directors and representatives of Spain's best engineering and technology schools. They were interviewed by El País regarding the challenges of training future engineers in Spain, especially as regards the specific characteristics of the new and demanding Internet and mobile applications market. With them was our VP of Corporate Affairs, Sebastián Muriel, and the winner of the first edition of the Tuenti Programming Challenge, Rosa Gutiérrez, who is now part of Tuenti's engineering team. Eighty percent of last year's finalists were later incorporated into Tuenti's team.

Deans and school representatives also visited our offices and absorbed the innovative atmosphere of one of Spain's leading technology companies.
