Initial screening interviews were conducted on my university campus with a couple of recruiters. Then, I was asked to prepare a presentation to deliver onsite. I was flown out to the Houston HQ for a day where I gave the presentation to a small group, got a tour, had lunch, and was taken back to the airport.

Friend discussion at first. Ask a lot of STAR type questions. Be ready for behavior (what if) situations. The Engineer asking me was understanding but the Manager was more challenging.
