My interview was quite simple. I worked for Gallup Organization right before coming here. I called and visited with the site manager and explained my job situation. I was told that I could not work at both, so I chose the one I felt I would be most comfortable in. Gallup, in my opinion, was too distracting. So I opted for the job that didn't have coworkers watching movies and playing games while working.
Basically had to go in, fill out an application and wait a day or two. Then met with the manager and read through a script for her. Really all there is to it.
