Avantages
You can learn a lot and the pay is good.
Inconvénients
Don't expect feedback on your performance. If they don't like something about your work, you don't get a chance to correct it. They let me go because of "lack of experience", when they clearly had seen my resume, and I thought I was learning very quickly. But the most frustrating part - no advice or feedback when I indicated that I would have really appreciated one.
