You will learn a lot about everything. From running a business to advertising products, to website management, you will learn it all. You will be very comfortable with the sales cycle and will get some experience with direct sales.
Cons
The pay does not reflect the work you put into this internship, and the hours can extend past what the description says on busy weeks.
You will always get to see the results of the work you are putting in, allowing you to easily track your progress throughout your internship. There can be a lot of work and responsibilities, but it is rewarding to see it pay off for the company.
Cons
Very time consuming, and quite the commute if you live in Austin.
