I applied online. The process took 2 months. I interviewed at Anglo American (Santiago) in Oct 2015
Interview
The first steps on the interview was basic e-mail exchanging directly with the responsible geologist (we were in different countries). I've sent many documents and was questioned about hypothetical situations in the field. A month later I was starting in the field and the experience was direct and good.
Interview questions [2]
Question 1
What was your previous experience in the field work doing exploratory geology in high altitude, staying in tents and with no comfort for a determined period?
