Pros
if that was not obvious ... flood of great reviews in last 1 month :) you can judge them from fact that its all praise n nothing realistic in "Cons" section... yes, there are good reasons to work here but I wont repeat those. I'd like you to join and enjoy yourself but just trying to help you with the facts before you join, rather than regret later.
Cons
They used to blame cisco openly earlier, which is bad. Now that they have hired so many cisco veterans and same culture growing here... same politics and job security tactics if you know :). Their products have lost the low-latency edge. With SDN there is no new breakthrough or technology advantage. In fact, ppl work on same features that are present in market products. The smartest of the lot have left for exciting places, if you know which. yes, you will make decent money with equity, but dont expect to retire.
