Also...go online and do a little research on Aflac (and their competitors) and all the different services they offer. I used to go online and look up interview questions too and kind of quiz myself (you'll get a good variety this way). You'll also want to be prepared with some of your own questions (this is when the research of the company comes in). Just be sure your questions aren't too personal (meaning, don't come across like all you care about is the money and how the hours impact your lifestyle...they want to see a give and take). Get those questions in there, but be sure to focus on professional questions. If you're applying for a position that you don't really know anything about...be sure to go prepared with a similar experience from your past on how you came into a position, learned the ropes, excelled, and felt a great sense of accomplishment (they like "go getters").
One BIG plus, especially if you're going to be working directly with the public...is to be sure to continually make eye contact and not fidget (don't stare them down though
.. Employers know people aren't necessarily their best at interviews because of nerves, but if you can exude a calm confidence...that can be very impressive.
Best of luck to you!
