Reached out to recruiter, set up phone interview with training manager, next interview was with managers, final interview was with senior manager and the director of the entire department. The phone interview is to gauge your interest, they must see that you have done your homework on the company and that you want to work for them. If your interest is passive, do not even apply. For the most part, all the interviews actually consist of you interviewing them. If you do not ask them questions and show interest, they will not consider you. That being said, it's important to be yourself and relax, your personality is what they are interested in most since they can teach almost anyone how to do the job. The in-person interviews are rather unorthodox, like I wrote, they are gauging your interest and assessing your personality more than anything. Don't feign interest or overdo it, they can see through BS and prefer people who are being real, not people telling them what they think they want to hear.
