Be careful. Part of their interviewing processs at Charlotte. NC is to put their prospective field engineers through a field call process where the the 3 interview panel members imitate customers that yell very LOUDLY at you. But they give you no pre-notice that this is what they are going to do. First time I ever had that happen in an interview. It's quite un-nerving if you aren't prepared for it. Actually, I am kind of glad I didn't get that job.:-D
