I worked at the company for 14 years; I had an extremely positive experience overall. The best part of working at Vonage was the people that I worked with.
Early on the opportunities and compensation were great but so was the work load as it was a rapidly expanding company, later on, as the industry caught on, things got a bit stagnant and with the addition of the usual Telco management red tape increased while favoritism and politics started to increase. Promotions were fewer and had longer gaps while compensation continued to fall behind market rates.
Still the company had excellent benefits and work life balance was well maintained making it a good place to work.
