I worked at Schlumberger full-time (More than 5 years)
Travel the world, often to very remote locations you would rarely, if ever, visit on your own.
Training is exceptional and particularly challenging.
Coworkers often become your best friends, many great people at Schlumberger.
Travel and work schedule often leads to long periods away from home and any family you would ever hope to see.
I applied through a staffing agency. The process took 2 days. I interviewed at Schlumberger (Houston, TX) in April 2009.
I was called for a Phone interview, then I came in for a face to face interview. The same day I saw 2 other interviewers. Next day , they sent me an offer package with drug test instructions and a offer letter.
Yes, they elevated my salary and vacation a little.
