From somebody who had the opportunity to take the test last year (unfortunately did not pass), here's some feedback:
1. Math test has 40 questions and you're given 30 min. to finish. Usually they give you a table with numbers in it (such as autos produced, company gross income, people traveling by auto etc) and then you get 4-5 questions referring to each table. Questions are usually related to percentages, ratios etc. For example, in 2010 by percentage how many more people traveled by auto than in 2009. You also get graphs and you have to get your information off the graph. Perhaps the most challenging are the currency conversion questions. They give you a table of what each currency equals in another currency. Then they ask questions like, how many yen will 1000 Euros buy you. What challenged me the most about this test was the time element, you have to work really fast.
2. Verbal test has 60 questions and you're given 30 min. to finish. You get 12 passages (each about 100 words) and 5 questions per passage. The questions ask about the passage and you have to answer true, false or cannot say. Of course the challenge is determining if it's "cannot say". Remember the answers have to be based on
what's in the passage, not what you know from common sense or what you have read. Here is an example from the SHL test site (SHL creates the tests):
A UN report has warned of the potential problems of global warming. If the production of greenhouse gases continues at the current rate, this will result in the melting of ice sheets in Greenland and The Antarctic. The consequences of this will be rising sea levels, which will endanger 145 million people. In response to the problem, the report observes the need for an immediate international agreement on reducing emissions.
Sample question: Greenhouse gases are produced in greater quantities in Greenland and The Antarctic, resulting in melting ice sheets in these areas. (T, F, C)
3. The personality inventory is, I think, about 40 questions and there is no time limit. I believe they were multiple choice and they would ask questions like: what would you most like to do on a typical Friday night: socialize with a few friends, read a manual on the B737, speak to 1000 college students, lead a meeting of private pilots. What I've heard from insiders is that they are looking for
consistency more than anything. In other words, if you are more of an introvert, don't play like you're an extrovert because you think that's what they want.
To prepare for these tests you may consider some great online sources that have a bunch of practice tests. They do cost some money but I think they are well worth it. The SHL practice site is free I think.
