Ventajas
Good way start .. if you are in a sprinting stage and don't really care about health, personal time, over all personality growth and ok to deal with what ever comes your way (work and otherwise). You will learn a lot (work and otherwise). Definitely a good place to learn life skills and priorities along with work. Dynamic environment

Biased management
Appreciation/Salary not based on or not related/proportional to you work performance
