Pros
Flexible schedule, nice coworkers, holiday parties, dogs. If you're fresh out of school and don't have any real bills yet, Sonic.net is a great place to learn.
Cons
Terrible pay, insulting raises. There are very few promotions, and they're based on the who you know instead of how you perform. The number of employees has tripled in the last 4 years, and management only has time to put out the biggest fires. The company takes advantage of the poor job market by keeping it's wages borderline unlivable. 401k is nice, but that doesn't matter much when you can barely afford the cheapest rent in the same town as your job. Dane is aggressively anti union. Years ago, he found out that some employees were thinking of starting a union, and he fired them all. Sonic is an at will employer, so they aren't bound by standard labor laws. I would recommend Sonic as a provider, but not as an employer.
