Team working is more about attitude and less about title and authority.
When you work in a team, forget about yourself and your personal expectations. Work toward contributing as much as you can and helping others completes their tasks. Once you are all in, the team will recognize your value and will take care of you. If not, then you can leave such a team with no regret.
If you are qualified enough and have the right attitude, there will always be great teams waiting for you to join them.
