The best job I've ever had. Hands down.

Pros

- True, meaningful benefits - Opportunity, not just as an individual contributor, but as an organization. We're solving interesting problems and are redefining the way people work and communicate every single day. It's nuts. - Leadership is incredible. These are people who have storied careers and know what it takes for a company to be successful in the long term. Decisions make sense. There really is transparency, which is a word a lot of Silicon Valley companies throw around but don't actually honor, and accessibility. You can DM or approach any of our C-level executives with anything and actually get a thoughtful response. Again, it's nuts. - People care about each other so much. SO much. I've never had so many people invested in seeing me grow and succeed, people who aren't even on my team or even members of my organization. Like... what? How do they even know who I am? - There's actual work life balance. It's another thing that a lot of companies tout, but Slack means it when they say they want you to work hard and go home. People have families and hobbies and gym memberships and friends and none of that has to go by the wayside or be sacrificed in favor of putting in 12 hours at their desks. - My coworkers humble and inspire me every day. These are multitalented, accomplished, brilliant folks, some of whom are truly thought leaders, and I feel so fortunate to have the opportunity to work alongside them. I can't stress enough how much I've learned. - I'm happy. Like, for real happy. Obviously people have bad days and there's no such thing as paradise on earth, but for the first time in my career I'm okay with getting out of bed in the morning.

Cons

- We've outgrown HQ and are spread across a few properties in San Francisco. It's a bummer not having everyone under one roof, but this is something folks are aware of and are working to remedy.

Pros

Great benefits (commute, health, etc.). Great culture and values. Helpful coworkers, embodying the company's values to help each other strive and produce the best quality work for customers. The company is the first advocate for employees' well-being (work-life balance). Oh ... and most importantly, a very diverse place (constantly aiming for better).

Cons

If you, unlike me, like a "nerdy" environment with less communication and exchange with coworkers, THIS IS NOT A PLACE FOR YOU.
