Avantages
Basically they pick newbies just starting in the industry and claim to teach them up but rarely do. It's learning on the job with no real courses being paid for so it's just second and third hand knowledge passed on. One time a client actually helped me in finding a fix. Without it their server would have crashed losing all their media. Believe it or not these are the Pros. You will learn fast, become more thick skinned to impatient, rude and downright horrible clients. When you do eventually move to another job you will have these skills to work from. This position is not for the faint hearted and weak willed. It will be long hours working 7 days a week. They don't request it, it's just part of the job.
Inconvénients
Read the Pros... you can either look at that in a good or bad light. Your choice. I wouldn't recommend this job but i will say that you need to go in with an open mind.
