Pros
If you're looking to work for a company with an exciting vision, a flat structure where you can learn and grow while having fun with a great group of people, well, this is it! Everyone works together to make a difference and there are lots of experienced and talented people within the company so you'll learn from the best. You can innovate, you can work without the classical corporate supervision and you can be part of a success story making a real difference for people.
Cons
Startups change as they grow so you'll need to be ready to adapt. You’ll also need self-discipline while being a self-starter. If not, then this is probably not the place for you.
