If you have something better, take it.
If you get hired to do customer service, don't expect any promotions or pay increases unless the management likes you. Some of the management think you're nothing but a machine that takes calls, and will write you up if you do one little thing incorrectly. Additionally, attendance is based purely on a point system. Doesn't matter if you get a cold or into a car accident, once you get enough 'points' you're out the door. The company also refuses to upgrade any of the systems and computers we use on the floor, so I hope you enjoy working with computers from 2006.
The employees however, are very colorful and interesting people, you will enjoy working with them as everyone gets along and supports one another. If you're decent at your job you will get fulltime or near-fulltime, and the benefits are pretty good for the position. Soft-skills such as communication and multitasking will be put to the test and heavily improved as you work here.
If you have something better lined up, please consider taking that over this company. But if you don't, it isn't the worst company to work for.
