Only thing required to start your Sys-admin career is knowing English in speaking and writing.
Cons
*non-transparent (micro)management
*low wages (well, since they recruit noobs, this can be considered irrelevant but later on as you progress, you salary doesn't rise so much)
*lack of training for new stuff
...
No previous experience required, you will learn the basics
Cons
No training at all, you will handle everything on your own and nobody cares if you do not know anything, despite the fact you are hired with zero knowledge. Stressful work with no downtime at all
