Full time employee of one year and I LOVE IT!
Pros
The BEST co-workers ever, a solid team environment, and the ability to actually make a positive impact. I leave work EVERY DAY knowing that I have made a positive contribution to my team, the company and more importantly the environment and future generation! I have gained a lot of exposure to the business and VP's within the company, even Elon! This is what it must have been like working for Apple and Google 15 years ago. Complete chaos but a one in a lifetime experience that I am proud to be a part of.
Cons
Yes, there is a lot of work (I have noticed that as a main complaint on here), but wouldn't you rather have a lot of responsibility than none? I could work all day and night if I wanted to, the work load is that heavy...but it is up to YOU to know when you need to go home and shut the laptop off. The company isn't going to close it for you. Create your own boundaries and the work-life balance will not be an issue.
