Pros
I really enjoyed my co-workers, and the upside of nonda being a poorly organized new startup is that you get a lot of autonomy and can develop new skills as a result. Also, the location in Palo Alto, free lunch, unlimited vacation time and the option to work from home are all great.
Cons
Do not work at nonda. You will absolutely regret it. The founder of the company is a terrible leader and the turnover at the company is CRAZY as a result. They hire and fire constantly, and everyone who works there is in fear of being fired all the time. There is a CEO under the founder, and he's a nice guy, but the founder is the boss so it doesn't really matter what the CEO thinks. He told one of my co-workers that he was doing a great job and then fired him a couple weeks later (after that co-worker disagreed with the founder).
