Pros
The biggest pro would have to be the experiences you get here that you won't get at 99% of other college jobs/internships. Before going into last year I never knew how to give a sales presentation. Now I can say that I ran a 53k business my freshman year of college, I can say that not only did I hire people but I got the unfortunate experience of having to fire someone, I can say that I processed a payroll and that I was in charge of up to 10 employees at one time. Also I made about 15% profit on my sales so the money was great too.
Cons
The stress level will also be more than 99% of the jobs that you have had up until this point. The big difference is now you are in charge of other peoples jobs and not only being responsible for your own. Customers will sometimes be a pain but that is the same for any job.
