Really try and branch out and help other teams, especially if you have a light workload at a given time. My manager wanted me to get as much exposure as possible. So when I completed my tasks for him and my team, I was always free to help others.
Also, definitely pay attention to managing styles. I was able to see how different managers managed their respective teams, and this allowed me to understand the kind of manager that is best fit for me (having a supportive manager is SUPER important for your career).
