Pros
Great personal and professional development. At ALPHAEON you are given all the training and tools you need to succeed. They offer ThinkAlpha classes which talk about mindfulness and the power of your thoughts, hold training on how to interview properly and look for top-performing candidates, and are constantly communicating the goals and vision of the company. There is no yearly review like at most companies. Instead, you have quarterly "check-ins" with your manager in which you drive the conversation about how you are performing, what areas you want to improve in and what tools you need to get there. My manager and I seem to have these kind of conversations daily, but hold a formal meeting quarterly. I have never felt more in control and focused on my career development. There are also plenty of snacks and food around at all times, but for me that is more of a con because I love free food and have zero will power. ;)
Cons
No 401k matching (every employee is given stock options instead)
Parking structure/walk to building deters people from getting out and about on their lunch break
