Recently, many companies have been conducting personality tests on future hires, either to make sure they will fit into the organization or to make sure they have the right skills for the position. These tests can range from a simple question and answer format to a job simulation, such as Agent Day in the Life.

If the company you're recruiting for doesn't have its own form of personality test, there are several available personality tests online, some of which are more unconventional than others. Many of these tests are free and do a good job of giving you some insight into a job seeker.

PsychCentral, a mental health Web site, created a list of the best online psychology tests. Some of the tests are used to collect data for research experiments, but others are skill tests or quizzes that offer personal insights.

The top 10 online personality tests include:

1. You Just Get Me - This is a social psychology experiment about personality impressions. You must test yourself on five measures of personality, which are based on the IPIP-NEO psychology scale, presented in a bubble graph and try to guess the qualities of other people while they guess your answers.
2. Bad Vibes - This is a sound psychology experiment from the University of Salford that helps you find out what sounds you think are unpleasant. You'll be forced to hear sounds such as fingernails on a chalkboard, babies crying and a dentist's drill. This could be useful to anyone applying for a job in a noisy environment.
3. The Stroop Test - This is a well-known neuropsychological test named after John Ridley Stroop. It tests how flexible and fast your thinking is by showing you the name of a color with the typeface in a different color, then measures how long it takes you to say the color and not the word.
4. FaceResearch.org - Developed by psychologists at The University of Aberdeen, this test allows you to rate the attractiveness of various characteristics, including facial, voice and different ages. It also asks you questions about your tastes and attitudes, and asks you to choose between two faces and rate images on a 1-10 scale.
5. The Concept of Intentional Action - Created by Joshua Knobe, a researcher from Princeton University, this test is based on experimental philosophy and asks what you think instead of assuming you think the way a philosopher does. It is meant to study perceptions of morality and intent.
6. Project Implicit - The Implicit Association Test uses sorting to see whether or not you openly express your social biases. The test measures interference between conflicting categories. It requires you to respond to words related to yourself and to others' faces.
7. Basic Music Intervals - This test, from Cognitive Fun, measures music cognition by allowing you to identify piano music intervals while listening and reacting to a visual interface. Obviously, this would be helpful to anyone applying for a job that has anything to do with music.
8. Face Transformer - From the Perception Lab at The School of Psychology at the University of St. Andrews, this test includes a collection of face perception experiments. The test makes you move a slider bar to morph computer-generated faces until they're attractive to you.
9. Visual Phenomena & Other Psychological Diversions - This is a collection of experiments from the University of Essex that asks you questions and shows you a graph of your results and a discussion of what is being tested.
10. Casual Fridays - This is actually a weekly series of online experiments from the Cognitive Daily blog. Every Friday, the site offers an interactive test based on research, news, theories and curiosity, with the results published the following week.
