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.
