The first thing I had to do was take an IQ test in 12 minutes. So my advice is to do some online IQ practice tests. On the day try to answer as many questions as you can, maybe the shorter ones. I read somewhere on this site you need to get 20 out of 50 right. I was told I did not get the job because I failed this test. A test that does not say anything about a person. A test that cannot assert if a person is organised and efficient. A test that cannot determine if someone has good interpersonal skills, are decisive, confident, capable etc etc etc I had to put myself in the companies position and ask myself If I had my own small business and had to interview candidates would I give them this test. The answer is no, it's a one dimensional way to judge any candidate. To say that someone who passed this test is smarter than someone who hasn't is absolute nonsense.
