Pros
318 offers anyone who's ready to learn new things a place to grow and do something different. You can dive deep into a platform (Mac, Windows, UNIX, networking, storage, development, cloud services) and become an expert. I've learned more here in just a few years than 10 years at my old job. But everyone is encouraged to become expert at customer and consulting services. Things aren't always easy and working here will definitely push you out of your comfort zone. I'm glad I took a risk and decided to try something different. My katana is sharper for doing so. My co-workers are some of the smartest in the business.
Cons
Your first weeks or months can feel like trial by fire. Onboarding is fast with little guidance beyond using internal systems. Operational procedures sometimes change on whim.
