It was a usual. Initial phone call was to contact the person to feel them out, after that was a half a day ride along with a tech that is closest to you. If that went well then you get a face to face interview with the regional manager which is also the hiring manager. Most things they ask are very simple, and with the use of common sense you'd do great. They aren't looking for the ones that know the most, they want someone they can trust, had honor and integrity. They can teach you anything you need to know, all you have to do is be courteous and professional.
