Written offer before an interview?

jrs....yes, an Aramco contractor.  Saudi Geophysical.  It is for a Operations Geologist (Geosteering) position within their Geosteering Center. I actually have a friend who has been in this position this past year that I am talking with there. Saudi Geophysical has passed my resume and application onto Aramco.  The contractor provides housing at their Rofana Compound, along with a car and fuel allowance.  They pay for all the utilities along with internet.  They also pay for Round trip ticket on economy class from Dammam - Home - Dammam, once per year for the employee and his family. They also provide Medical issurance.for employee and his family.  They pay the employee as a Day Rate where Aramco counts it as an hourly pay.  Day Rate of 600 USD (2,250/-SR) per working day. They even shared the work schedule for this position since it is a technically critical position.

Work Schedule: Three 8-hour rotating shifts.  7 days on / 2 days off (5am - 1pm); 7 days on / 2 days off (1pm - 9pm); 7 days on / 3 days off (9pm - 5am)

@ knyxxx ----My friend that works there for Saudi Geophysical said that when the contractor reaches out and sends our resumes onto Aramco, the people usually do get interviews with Aramco.
