I applied online and was contacted within 48 hours. The first call is made by one of their HR representatives at their office in Plano, TX. It seems fairly straightforward - if they call you, you've essentially been chosen based off of your resume and representative is most likely judging your character. After a brief discussion they'll want to know if you're willing to move forward after you've learned what they tell you about the in-depth details of the position. Afterwards you can expect a few email/document exchanges with a higher manager and information on the training.

Applied online, phone interview process. HR Rep was very nice. Followed up with another individual. He was also very nice and professional. He emailed me documents to read and sign to set up training session.
