Pros
The management (one individual in particular) is incredibly fantastic and will go above and beyond to help the employees in any way they can. If you are looking for a start in server administration, have little to no experience, and have a drive to learn, this is the place to start. They will train you on what you need to know (although the onboarding process is a bit rocky) and give you the resume experience. You can work here for 6 months to a year and then leave for another company making significantly more money. There are actually other IT companies in the Orlando area that actively seek and snipe Atlantic.net employees. If you have their name on your resume, you'll be in good with other hiring companies. Management is wonderful, I really cannot stress that enough. All the teams above you (cloud engineers, tier 3, network engineers, etc) are wonderful people and more than happy to help with confusing situations. If you show a genuine desire to learn, rather than just pushing your work on someone else, any one of them will help in any way they can.
Cons
Incredibly non-competitive wages plus no raises (not even cost of living) means that you will never make another cent more than you're making when you're hired. Hint: it's the same salary they've been offering for the last 6+ years. The owner of the company absolutely does not care whatsoever about his employees and their loyalty. He has point blank told employees to their face that they are replaceable and if they want more money, he won't hesitate to find someone else who will accept the wages. There's a member of staff who has been a loyal employee for 5 years and the owner does not know his name. In a company with under 30 employees, this is laughable at best. The company is constantly understaffed (due to the aforementioned ability to train and then leave for more money elsewhere) so the schedules can get hectic when employees quit. You have to be grossly incompetent to be fired there, which means if you're not one of those people, you have to deal with them.
