BBC Personality Test.

The BBC has a whole slew of Surveys and Psychology Tests that tell you all sorts of things about yourself. I find that this one was pretty fun to take and definitely described me well. Every single subject it said I was half this and half that, pretty much I am in the middle of each extreme, which is pretty much how I feel about things.

My Results
Extraversion

Some people like lots of stimulation; they want people around them, activity and excitement, whilst others prefer to be able to focus on things in a calm and quiet environment. Most people prefer a blend of the two extremes and your answers suggest that you are quite comfortable in either situation. You can probably cope with things being a bit hectic or a bit quiet but, like most people, you may find extremes in either direction uncomfortable or annoying.
Confidence

Some people make decisions very easily and tend not to worry about them before or afterwards while, at the other extreme, some people are so careful and cautious that the decisions never get made! Taking a cautious approach can be a good thing (do you want to fly with a pilot that is so free from worry and concern that she never checks her controls and instruments and doesn't bother to communicate with air-traffic control?) and you seem to have described yourself as someone who can be careful at times but is also prepared to take a few risks. This can help you deal with a range of settings and decisions but, like most people, you may feel uncomfortable if you have to work in very risky environments or if you have to be very detailed and thorough for long stretches of time.
Openness

While some people like experimenting with new things and ideas, others prefer traditional methods and taking a very practical approach to problems.

Your answers suggest that you like to balance a willingness to try new things with making sure you don't scrap an existing approach that works just because it has been around for a while. Like most people you may not enjoy constant change and uncertainty or an environment where nothing develops from year to year, but your preparedness to see the merits of new and old alike can be helpful.
Agreeableness

Most people want to be able to get on with others but to some it is the most important thing in the world, whilst others are quite happy to upset someone else if it means that things get done.

Your answers suggest that you can be firm with people when you need to be but that getting on with others is still important to you. Like most people you would rather avoid conflict but are not prepared to put up with being treated badly by others.
Conscientiousness

Some people like everything to be well planned, tidy and organised, whilst others prefer to deal with things as they come up and appear to work in absolute chaos.

Your answers suggest that, like most people, you like to have a little clarity about where things are but that you would rather cope with some things as they arise than spend too much time sorting out every single detail. This approach may help you when working with teams and also when having to deal with those situations that you just can't plan for.
