Pros
Fun, fast pace environment where one can learn a lot. Excellent benefits package, free gym membership, fun work-social events, great location, wonderful people.
Cons
Not enough management training. People are promoted into management roles without adequate training. Not referring to skillset training, but human interaction training. It is good to promote from within, but not everyone is a good leader. There are numerous examples of tyrannical behavior that has occurred when this mistake has been made at Bandwidth. These managers are ultimately moved into another role where they no longer supervise people, but the damaging effects are still there. The whole "boys club" mindset. There are numerous references to this in Glassdoor reviews, so no need to go into it too much. It is more like a popularity club, similar to cliques in high school. HR. Not only has it been speculated that HR writes fake Glassdoor reviews, they are also not the best fit at their jobs. Not all of them, there are some good ones at Bandwidth. But there are also some horrible ones.
