Pros
Spiceworks moved into a new building about two years ago and it's really nice - very modern and kept clean. There's free snacks, coffee, sparkling water, soda...the snacks even change out from time to time. People there are (generally) friendly and I've really enjoyed working with most of my co-workers. There's a lot of ownership given to you if you show that you're willing and able to take on more. No micromanagement in the team I worked on.
Cons
I think some people who work at this company let their high-ranking position get to their heads. A lot of the more difficult interactions I've had with people were with the senior-level employees. To Spiceworks' credit, they have let go some employees who were repeatedly reported for their behavior.
