A few tips: 1. Familiarize yourself with their values 2. Don't take the test if you are tired, it takes thinking and a good amount of mental energy 3. Make sure you are alone and in a quiet room - they use some audio for the interview 4. If you are bad and math/statistics - review some good old formulas, especially those that include percents, division, etc. 5. While it is a good opportunity try not to get too excited until you get an offer. Many of those who applied did not get thru because there are so many steps. Good luck!
