Pros
I started at SPINEN only a year or two out of school, and was trained up from being a very green technician, to a team lead and later a middle-manager. The main thing I love about SPINEN is the people---We have so many different personalities, and it's not "cliquish: the prerequisite to being a good fit is really looking out for the client and each other, being honest and owning things (good or bad), and having a lot of initiative to learn. We are continuing to train up an awesome team of employees with relatively little real-world experience, and seeing the team continue to grow and thrive is so great. I also love the fact that I've gotten a lot of experience with different tech. We work heavily on just about every area of a network (networking, PCs, servers, phones, etc), and although we try to stick with certain reliable brands, we aren't pigeonholed and have opportunity to touch things that would be off-limits in a really large environment. (Like SAN infrastructure or Group Policy creation.) Most of what I've learned here has been on the job, though there's encouragement towards certifications and incentives around them as well.
Cons
We are extremely busy, and sometimes volume can get a little overwhelming, though I think this is the case of "too much of a good thing" and something we can deal with by adding more people and better use of automation.
