Pros
After working with SC for less than a year, it appears that there are opportunities for advancement for top performers (who can navigate the politics well). Company is growing. As a Field Energy Specialist generating leads in Home Depot, I have *a little* control over my income if I really hustle and am good at sales. Also, my direct supervisor is great, but I hear this can vary a lot. My numbers are high, so that's good I guess. Oh, and SolarCity seems to have a successful and innovative business model that leads the industry. So there's that.
Cons
The culture is very "bro-centric." No women in C-level positions and very few women VPs. Some top level execs (e.g. CRO) regularly uses 4-letter words and sexist language on company-wide sales huddles, which can be alienating. "Coolness" seems to be valued over education or intelligence. Very little control over your commission/livelihood, since leads are handed off to consultants who may or may not close your deals. Standing on concrete 40 hours/week. The job is simply lead gen, so it can quickly get boring. Lots of contests to hit high numbers, which you'd think would be a "pro," and it is to an extent, but contests with nearly impossible goals aren't motivating. Plus, not everyone cares about white water rafting trips. Profit-sharing/stock options and 401k matching (i.e. respect for all levels of employees) for quality work would be much more motivating. Alas. Other than an employee referral program, no such things exist. As an FES, you will be required to work all day every single Saturday and Sunday. There is very little, if any, wiggle room on this. That makes having an adult life (for occasional volunteering or reunions or weddings) not a possibility unless you use your limited vacation time.
