I applied in-person. The process took 4 weeks. I interviewed at NIC Mexico (Monterrey, Nuevo León) in Apr 2014
Interview
I went to the company and left my resume saying I want to apply for the marketing intern position. That day in the afternoon I received a call asking me to come the next day to an interview by HR. After that I passed to the interview with the Marketing Manager. Then it took like 2 weeks to have the interview with the Commercial Director.
