I worked at América Móvil (Less than a year)
Huge organization, large reach, takes a time to get things done
Not a lot of mobility, promotions by tenure and merit but it takes a long time
Advice to Management
Move people around to avoid stagnation
I applied online. The process took 1+ week. I interviewed at América Móvil (Coral Springs, FL) in April 2012.
Extremely easy and relaxed. They seemed like they didn't care much about you or your goals but more about filling a position. HR wasn't very responsive or attentive. They were focused on hiring someone that spoke both Spanish and Portuguese
