I saw this really amazingly done interactive infographic about the top companies to work in the US.
What’s great about this infographic is that its a really a presentation with excellent choices made for presenting a large data set. You can see what employees say about these companies. You can dig deep at each companies level to see what employees value about that company.. for example Google employees value free massages and catering.
Take a look
