I applied through college or university. I interviewed at Meta (Ciudad de Mexico) in Feb 2017
Interview
You make two phone interviews and then they tell you if you have an offer. On each interview they give you one or two problems, one behavioral question and at the end you get to ask the interviewer anything about his experience.
The interview was based off practical tools & testing proficiency with the Facebook platform; mostly online and some via phone. Lots of feedback & testing both ways, product improvements, enhancements.
