Ventajas
Good salary, insurance and pension. The work guidelines are clear, international colleagues, and good exposure to senior management from the start (in a "BAR" / "BAP") position.
Desventajas
Repetitive work, limited moving opportunities, no internal job market (superiors decide on job moves, and you say "yes"), uninspiring atmosphere. One major con is the fact that before starting, the job was very well promoted during interviews, however, little was explained about the actual work. I.e. in the "BAR" / "BAP" jobs, everybody works on a fixed monthly schedule, closing monthly books; thus the job is close to accounting and requires much research of bookings in SAP. Also, before staring you should ask if you will be a 'business' or 'controllers' resource; it will determine the direction of your long-term career. Switching is possible, however, very uncommon.
