If you're smart, you will leverage the environmental factors during your internship.
You have a number of resources starting with your boss and your team. These people can of course serve as great mentors, and they will also form your network in the future. Watching a good mentor do their thing is very powerful exposure. Colleagues with high caliber, passion, and energy also serve as great role models and energizers.
Next, the company culture is also something you should pay attention to to understand what aspects you like or don't.
An internship utilized in the right way is an extremely powerful opportunity.
