Pros
This is a fast paced environment and a good way to increase your confidence and skillset. Plenty of responsibility and high-end linux problems to solve.
Cons
Little authority, overbearing management, constant micromanagement, fake 'fun' environment covering up a cheap, stingy attitude towards technical professionals. Constant infighting, terrible food, substandard workstations, constant system errors, shady marketing practices. Hostgator is a complex pyramid scheme built by screwing over resellers and bilking customers. Don't expect to like yourself much after a day of treating customers like garbage. Strict quotas mean actually helping people is nearly impossible. Over-competitive environment makes forming friendships and professional relationships difficult. Dog-eat-dog corporate culture reinforces paranoia. If you work in the Austin office be prepared to be ignored and undersupported. Managers generally don't know what's going on, constant brain-drain as unappreciated technical professionals leave for better opportunities.
