Pros
Plenty of great co-workers and opportunities to learn—you'll be encouraged to approach problems in a new way. It's a lovely office, and the relative transparency with where the company is going makes it easy to feel engaged.
Cons
Reviews that call RH a cult are true, as are the reviews that rave about the place. It's all of those things. Your experience will depend on who you are and what you're looking for. The people who seem to do best at RH are the ones who are always available, who can navigate the culture that is overtly made in the image of the CEO (which is to say, who parrot whatever the CEO says as if they said it themselves), who can recite every word of the vision, values, and beliefs, and who are comfortable wielding influence through fear. If you are invigorated by long hours, values meetings, and publicly pledging allegiance to Gary Friedman (and all of those things are OK if that's for you), you'll do well at RH. If you like stability, to have at least a general sense of what is going to happen tomorrow, space to speak freely without being immediately shut down, and going home at a reasonable hour without worry that you're going to receive untold number of texts and emails while you are with your family (and all of those things are OK if that's for you), RH is not for you.
