Application Process:
Over a month after applying I received the first call from a recruiter. Went in the following week for a scheduled test. The test consisted of both basic math and interest rate/principle calculations. In addition, there were a few customer service call simulation scenarios. The test was immediately followed by a personality trait quiz (how do you handle conflict and criticism, are you a leader or a follower, etc). Following the test, I was advised that I passed and was invited back for an interview.
Interview:
As most interviewers would, they will likely start out the interview with "Tell me about yourself." Have your USP (Unique Selling Proposition) prepared in advance. This would consist of your name, your past relevant job experience, and what you hope to bring to the company. Don't be shy as this would be your main opportunity to set a great first impression and to really sell yourself. Be concise and don't ramble.
Additional Details:
I didn't hear back for another ~2 months. They typically (based on my discussions with other employees) won't start to make offers until the class is scheduled and they're filling the available training openings. After my third follow-up call in two months, I found out that the interview went smoothly and that I was on the waiting list to 'class-up'.
