I applied through a recruiter. The process took 2 months. I interviewed at Petro Rubiales (Panamá) in Jan 2015
Interview
Very quick process, nice treatment. It took time because they were opening the new office and preparing the expat people for the initial operation.
There was a modern process of communication, met in an opened public place, also connected via skype with HR´s Managers. Linkedin was very helpful also.
