One, two, three... Four!

The expressive style (25%)
The expressive loves dealing with people and teams. They volunteer to be in the center of any enjoyable and challenging new activity as long as doing so involves interaction with others,
The expressive loves change and love the excitement that working with others on new projects can bring. In a group, expressives are happies when they're the center of attraction.
They may be excellent motivators and barnstormers but they are often not strong on detail or follow-though. They may lose interest quickly and are usually not confortoble tackling complex, long term projects or assignments.
Note that, in most cases, being organized is not one of the expressive's strong points.
Where you're likely to find then. Careers that suit the expressive may include marketing, sales, public relations and communications. They may also be CEO's.

The analytical style (rare birds, less than 5% of the CEO')
This personality loves to deal with facts, figures and details. They prefer a process in place of interaction with another person or team player. They have a low tolerance for mistakes, misinformation and malfunction. They do everything "by the book", you must prove that you understand the rules and demonstrate that you are willing to play by them. Never cut corners. Always understate and overdeliver.
Always respect and follow terms and conditions. In other words, have the integrity with the analytic."

The amiable Style (10%)
The typical amiable style is caring, considerate, concerned and always available for a friend or colleague. These people are great listeners and nurtures, As a general rule, amiables don't like to be in the lime light. "I didn't want to bother you or interrupt the meeting, but I'd like to make a suggestion if I could..."
If you want something from an amiable, emphasize what contribution the amiable can make. Don't ever taske an "amiable" to "take sides".

The driver style (surprise surprise : 60% of the CEO's)
Drivers love to lead; they love being in the pressure cooker; they love calling the shots stress is their middle name, action is their game. They like to make snap decisions and sort problems out later. If any of the four groups are attracted to empire building, it's the driver group.
With him : Be brief, direct and to the point, don't challenge this person's autority unless you're ready for a major conflict.
Don't ask question that force the driver to admit he or she doesn't know something : The exchange will stop cold focus instead on what the person is trying to accomplish and make suggestions based on that you hear about that objective. 

And now, ladies and gentlemen, who are you? Amiable ? Or a driver? May be an expressive? Or an analytical?
