When I interviewed for my current job, I had to take psychology test and I'm very skeptical to those kind of tests. The guy that ran the test explained that this wasn't about putting me into a colored box but trying to figure out what I naturally preferred to do in a work situation with the idea being that things that I enjoy are probably things that I'm good at because it takes less energy to perform. I don't know if it works but it's an interesting idea, things that takes less energy, you do more and you're probably more proficient at it.
