Pros
Amazing culture, they are all very positive and focused on achievements and growing your career. Management really cares and is very invested in the individual's success. They are really supportive of taking your own initiatives and doing passion projects while at work. They are open to all kinds of ideas on how to grow the business and provide better customer experiences. They really do follow their core value of "where the best get better" in supporting the individual contributor and leveling them up. Of all the companies I've ever worked for or with, the most striking difference is that WP Engine actually is guided by its core values. And it even affects the sales teams - where often the sales teams have a completely different culture than the rest of the organization, sales is much more closely aligned with the overall culture at WP Engine.
Cons
At least in sales, the pay is lower than the standard for a downtown, technology outside sales role in Austin. They hire in sales one level down from matching your current level of experience and achievement, with a carrot for promotion in 6-12 months. Most solid sales reps are not intimidated by the opportunity to prove themselves both in their sales acumen and their business contributions. However, this promotion rarely happens in under 1 year unless there is a perfect storm. So if money is important to you, this might not be the best fit. They promote over-working and don't have a good work-life balance for the sales teams. It appears that other departments do liberally use the "unlimited" PTO, etc - but for sales, that rarely occurs. If you want to consistently keep it under 50 hours a week (when not traveling), that isn't going to happen at WP Engine, if the sales reps want to hit target.
