Pros
Veteran Web Experience, lots to learn and great mentoring from the company leadership. The web projects are generally more complex than other agencies I've worked with, so it's a good place to keep your skills sharp, level up and develop professionally. I started there with website updates and bug fixes, but by the time I left I was working on development teams and making engineering-based decisions for sites and software.
People there really care about what they do and are largely supportive and helpful, and the technical standards are high. It's a smaller company, so you get to work with pretty much everyone and that was a plus for me.
The company has been around a long time so it's stable compared to some smaller agencies and has good benefits and location, with an easy commute.
Cons
Smaller company, so opportunities for senior career advancement might not be internal unless the timing is right. Leads/Directors don't micromanage your work and expect you to complete it, but this sometimes means you have to ask for direction instead of just receiving instructions. Sometimes the hours are long (especially around launch dates) but it's not a constant thing.
