Ventajas
There aren't any "Pros" to speak of. Honestly, I cannot think of any.
Desventajas
This list could take forever to write. I'll just sum it up by stating that the management is seriously corrupt and do not value hard work. I worked there over 5 years and never advanced, even after consistently receiving great reviews. You have to ask management for a performance review. If you do not get a review, then you do not get a raise. Also, it seemed like when I would request a review from management, they would always be "too busy" or reschedule multiple times (at which point most employees would just give up). Most of the employees who are in a supervisory or managerial role are family and/or friends of other managers. There is a serious nepotism problem. The list goes on. I need to stop here. My best advice is DO NOT work here unless you want your work-life to be a living hell.
