I recently participated in a job interview in which I was required to take a "Test." It was basically a 30 minute test, with questions ranging anywhere from identifying the one shape that doesn't belong with the rest, to basic geometry and word problems and the typical "glove is to hand as hat is to what?"- type questions. Throughout my interviewing period, I have completed many profile/personality assessments, online exams, writing tests, etc.
I believe that this is a trend which will continue to become more prevalent, as more businesses start to not just trust what you say about yourself and your talents, but also to see some hard evidence that you can actually do some of the skills and possess some of the talents you admit to having. The purpose of these tests, I believe, and anyone feel free to add to this, is not always even designed to measure your skills or knowledge, but rather to analyze the steps you take, and your thought process, for solving a problem. But in taking these tests, this is a time to let some of your greatest talents in your inventory stand out, like showing organization, prioritization, time management, creative thinking and logical reasoning. I have discovered these types of traits to be the most important testing objectives for many of these tests, and think they are good tools to measure them.
