Here is an online game that I am playing. My task: To water my flowers and to defend my “contraption”, on the right side of the screen, from the burny thingies that march over the hill from the left. My weapon: water balloons that I can fill on my contraption (until they sometimes burst) and flip (with a swipe of my finger) at the hot enemy hordes, thus extinguishing them. The challenges vary. Sometimes, there are just a few fiery intruders. If I throw high and hard enough, I can catch them as they first enter my space. Sometimes, though, I miss them. They toast my flowers and come right up to the foot of my contraption, trying to burn it down. No time to fully fill balloons then. Just a quick squirt and then fling, fling, fling the flaccid bags down to protect the contraption base.
How well I performed, through sixteen challenges, may offer a clue to where my strengths as a worker lie. Am I a strategic thinker? Am I quick? Do I think ahead to protect the flowers at my base when there is leisure to do so?
The game is called “Balloon Brigade”, available as a free iPad or iPhone download from Knack (http://knack.it), a San Francisco-based company that aims to analyze potential employee strengths based on game play.
