Pros
Good package: competitive salary and benefits including gym and weekly lunch. It gives you the opportunity to accumulate resume skills and experience working on a good idea before moving on to your next job.
Cons
The worst of silicon valley's startup culture. A bunch of dudes with aggressive personality, no skills on the technology and too much arrogance to admit it. High personnel rotation is always a red flag and Fan TV (previously Fanhattan, previously Vuze, all the same people) has actually decreased in size. Quite a few talented engineers have come and go, they hire talented people but they won't let them do their job because the founders need constant reassurance of "authority". Not only my case, but other cases of employee dissatisfaction were handled badly by the CEO and the rest of upper management.
