It's not a test! There is not a right or wrong answer. It shows areas where you are strong, average and areas where you need improvement. It could be communication skills, critical thinking, decision making, etc.
The test also shows deception based on your pattern of answers. Why would you not want to be honest? The only reason would be you aren't confident in your abilities. If you lied and ended up getting the position, you don't have the necessary skills and you would not be successful.
There are 3 outcomes from most personality profiles. Recommend, recommend with reservations and do not recommend. The majority of people are recommend w/ reservations. It recommends them for the position and shows areas that the employer can help you improve upon.
