The first thing the owner told me in my initial interview is that he's not a micro-manager. Lie number one of many to follow while I was employed here. Everything, and I mean literally everything, you do in the office is watched and tracked and then followed up with disciplinary action so the owner can cover his bases when he fires you.
The owner's business practices are tainted with the same deceit, lying directly to clients and obtaining business data in unscrupulous ways. I didn't really like doing the work at times because it felt underhanded.
There are no Pros/Cons of being a fast paced environment. That's every company I've worked for as a web developer, the same for my freelance clients. They're called sprints and deadlines. Wearing many hats and team crossover is part of being a web developer too, so the other fake positive reviews here are just that, glaring fakes written by the owner's dummy accounts attempting to post false Cons and boost his rating.
Lastly, I agree with the other reviewers here: The two partners that own this business are disrespectful, condescending, unprofessional, and moody. The well is so tainted here that other employees were telling me on day one that they were sick of their job here and wanted to leave because of the owner.
