One of the first things a career coach might ask you to do when you begin working with her on a career change is to take a personality assessment test, for example, such as the testing developed by The Myers & Briggs Foundation. These personality tests are intended to gauge how you interact with other people, how you think and how you work, and then such tests come up with a personality type. In theory, different personality types are best suited to particular jobs, so the test can give you a sense of professions you might look into.
The brief quiz below is a sample of a personality test that you can try. It is not based on data from or affiliated with any formal testing service. Also, the quiz is not meant to be a substitute for any formal testing program.
Note: While personalities differ, they also share similar qualities. For example, an INFJ and an INTJ will be very much alike, as they only differ in the thinking and feeling profile. Thus, many career fields are suitable for many different personality types.
