[Update: The app is currently only available in Sweden. The global launch timing is still to be announced.]
With open job positions in Barcelona, London, Stockholm, Malmo, Bucharest and even Tokyo, King's human resources department is clearly busy.
But it's not too busy to have a little fun.
That's where the King Challenge comes into play.
It's an free app that will test your skills in a variety of different roles - from Java, ActionScript and C++ to data science, marketing and business - encouraging you to see if you can claim the throne via answering a series of relevant multiple choice questions.
In order to do this, and open the 'secret door to our Kingdom', you need to score at least 90 percent.
The King Challenge is available on iOS [App Store link] and Android [Google Play link].
