NOV Service Tech interview questions

I got a phone call from a NOV recruiter and scheduled a face to face interview. The face to face interview went well. I was asked simple questions about my experience and familiarity with downhole tools such as MWD, mud motors and various other equipment used in drilling. I did have previous experience with these tools because I worked as a roughneck for a drilling company before. I am also a military veteran and I also had a degree in mathematics. They seemed very interested and I of course was interested in working for Varco. They did explain the work load which was 12 hour shifts with lots of overtime which is what i wanted and expected given the nature of the job and the industry. They gave me a quick tour of the warehouse and informed me that they will keep in touch. I never heard from them after that. I have been applying at NOV for nearly 3 years now and this was the first interview they have ever given me. They certainly missed out on a great worker.
