I applied in-person. The process took 5 days. I interviewed at Gustavson Associates (Boulder, CO) in Jan 2011
Interview
I had to meet with the president, chief economists and lead petroleum engineer to discuss very technical and indepth questions regarding petroleum engineer. The interview lasted about 30 mins and covered reservoir and drilling engineering. All in all, if one is prepared then you shouldnt have a problem although it is very technical
Interview questions [1]
Question 1
Describe reservoir systems that you have worked with?
