Pros
You might end up learning a lot of things, but even that is a result of work being dumped on you, as you have no other option.
Cons
This company will destroy your mental health and your physical health. It will also make sure that you have got no life outside of work. They will assign you so much work that burnout would be the only possible outcome, which explains the extremely high turnover rate here. There are people leaving and being hired pretty much every week. All they care about is their nasty, unrealistic, inhumane deadlines that are impossible to accomplish unless you give your whole life and soul to the job. There is no training about the actual work either, and you're supposed to figure everything out on your own, while still meeting the weekly deadlines, all amidst a disorganized workplace.
