Was contacted through the Nicholas Charles company and phone interviewed with them, they basically made sure you were able and willing to work the long hours associated with being a field engineer. About a week later I had another phone interview with a woman with a French accent, who seemed to be accustomed to people having trouble understanding the accent. Interview consisted of mostly normal questions (asked to talk about yourself and highlight important things on resume) as well as some oddball questions (the 7 ball question with one weighing slightly differently).
