Pros
Very talented and well connected executives. Benefits are good. Stock options are especially lucrative for those who have been working for the company since before the IPO. But either way, its nice knowing that everyone is a part owner in the company. Expect to work side by side with positive people who enjoy their jobs. SolarCity is a good opportunity to learn the ins and outs of the solar industry. The company does a good job of promoting from within, while at the same time bringing in outside talent when necessary.
Cons
Right now, middle management could be stronger. SolarCity grows very rapidly and is forced to hire very quickly. Unfortunately, with the current model, they can not afford to be a company that's slow to hire and quick to fire. At times, the company has no choice but to hire or promote someone that is not quite qualified for the job yet.
