I only had two interviews in 30 years in the oil industry. One didnt have a job at all so no surprise I didnt get it. The other was my first in Saudi, I went into their offices near London after having three medicals in Harley Street (where all the expensive London doctors are). The guy said "what are you here for" and I said "an inspectors job in Saudi Arabia". "Do you want it" was the next searching question. Two weeks later I was on the plane.
