Vantaggi
In my department, we were able to make our own schedules, and I still miss the 4-day weekends that I had every week. The job itself was not difficult (and we were given plenty of time to get the hang of things during the training process) and required absolutely no sales. The management of my department was excellent. They did everything they possibly could to make the atmosphere as employee-friendly as possible (well, except for pay more). I would highly recommend this company (or at least this department) to students or anyone looking for part-time work.
Svantaggi
There's no sugarcoating the fact that the pay was very low. Also, since it was a part-time job (the company's decision, not mine), there were no benefits. This is the primary reason that I ended up leaving. To management's credit, they were very upfront about these realities during the interview process.
