Applied online for the field engineer position in August 2013. In november they sent me an invitation by e-mail to invite me to an assesment. The day started with a company presentation and continued with 3 tests : Math, Mechanics and Logic. Each test has a completion time of 40 minutes and they are given one after the other. So this is challenging because some of the questions require some time to think them through. Unfortunately my score was not high enough and for me the assesment stopped there.
