Pros
Down to earth founders who really care about their employees and visit the sites giving employees a chance to meet them and ask questions in person. Health insurance premium covered at 100% with extremely low deductible. Free lunches, snacks, and drinks. Great common area for chilling out. Lots of events happening at all times. Music or movie playing in the common area most of the time. Unlimited vacation.
Cons
Lots of people with huge egos who like to have a say in everything and like to criticize for the sake of having an argument. Management at the Austin site seem to have known each other for a long time and act very cliquey. No well defined career path for growth. Hard to find space where you can quietly focus on your work. No positive feedback given by management for a work well done. Austin site grew too fast and things are a mess when it comes to process and structure. People managing the process and structure don't seem to like doing either.
