I worked at PacketZoom as an intern (More than a year)
As an intern, there were various learning opportunities. If you are interested in computer networks, you can rest assured that you will definitely learn how networking is done. You can be exposed to various stack of the technology and also how a startup functions.
Programming languages ranges from Frontend to Backend Languages (includes Golang too - if you are keen)
Feel free to ask questions. Everyone there are open to sharing!
Downside? You would probably have to be a fast learner if you want gain as much knowledge as possible.
