I applied online by filling out the application and sending in a resume. About a month later, I received an email to do an online assessment/video interview. The following day, I was offered to go to a face to face interview in Knoxville, TN that next week.
I suggest looking at ALL of the interview questions on Glassdoor ahead of time and preparing your answers. Everything on here was asked of me in the interview.
The interview was on a Friday, and I received my job offer that Monday. I accepted, and am waiting on my training date to be assigned.
If you prepare your questions/answers ahead of time, you will do great. I felt very confident in my interview.
