Team Roles Test
I have conducted a Team Roles test to see where do I belong within a team with my own personality. There are 36 options that we need to choose based on our own personality.
The result of my test is as in picture below.
The result that I got is that I am an Expert. The expert has the skills and expertise required for the specific task at hand. He or she has a strong focus on the task and may get defensive when others interfere with his or her work. The expert prefers to work alone and team members often have a great deal of trust and confidence in him or her.
