Pros
CleanEdison gives employees the opportunity to manage themselves. You need to be able to take on a variety of responsibilities and accomplish tasks efficiently. But if you can learn to work in the startup environment, you'll gain more experience here than in any larger corporate operation. The office is young and all employees and interns are great people who you'll love working with and hanging out with outside of the office
Cons
As anyone who has worked in a startup knows, some days are going to be extremely stressful. You have to work within a tighter budget and on shorter deadlines. Because the company is small, you need to be able to communicate effectively with everyone in order to run things smoothly, and you need to be willing to pick up the slack even if it falls out of your department. If you're willing to adapt and run with the freedom within CleanEdison you'll learn a lot.
