If there is one thing you don't joke about at Logitech, it is Halloween. The preparations for this celebration start months in advance in the secrecy of the conference rooms. Each department prepares its war agenda. The goal: get the trophy of the best decorated area, best skit or/and best group costume. And when you step in the building on October 31st you'll be blown away, unable to recognize the place. I think some even never find their cubicle on that day!!
