I sent in a resume a few months ago on a lark --- not even a cover letter. I was shocked when they called and asked me for a phone interview! The phone interview was not very out of the ordinary: a few behavioral questions and brain teasers. By the end of the phone interview, the recruiter had already made up her mind that I was going to be flown in for a second interview and confirmed the date for that. Two weeks after the phone interview, I was flown down to Texas and put up in a nice hotel. The on-site interview was just as described by other posters on this site (in the interest of not being redundant, I'll gloss over this). The first night we were up until 3AM doing presentations and team building. The next day we went on a site visit for most of the day and then had an exit interview. I got about six hours of sleep over the course of two days, but it was also a fun ride. My advice to people about to interview: 1. Get lots of sleep before you go down there. You're going to need it, haha. 2. Have some enthusiasm. I can't stress this point enough. The group I was interviewing with had a lot of quiet people that asked no questions. As a field engineer, you are not in a cubicle by yourself all the time. You need to show that you're the kind of person who can think on their feet and interact well with people. 3. Remember that you're ALWAYS being evaluated. During my interview, they asked for volunteers to clean up some of the equipment at the end of the first night. By the end of the night, it was 3AM, and one of the volunteers just completely blew it off. All of the recruiters noticed. Keep things like this in mind. 4. Look at the benefits package for every job you interview for, not just the salary! People right out of college make this mistake and companies know that. SLB gives you three weeks of vacation as a new hire, so that's really nice. They also have good stock options and 401K matching. Good luck!
