Pros

Great office culture and teams that really believe in the Slack values! Kindness, collaboration, and craftsmanship are visible in almost every interaction you see on a daily basis. Awesome perks and a huge emphasis on a work life balance makes it a pleasure to work hard and go home at the end of the day.

Cons

Career and promotion paths are still in the process of being formalized, but good news is that this in being worked on a lot by management.

The Nicest People Work Here

Pros

1. We use Slack rather than email for internal comms. No intranet either! Amazing. 2. The culture here is unlike anywhere else I've been to (in my 12 years at tech companies). Lots of "important" things that are campaigned heavily at other companies such as Diversity & Inclusion can make corporate employees feel numb or apathetic but at Slack, D&I is a real deal. It's not just talked about or inflated - there are real practical plans, processes, and engaging events that show D&I is part of our daily work lives. For example, very rarely will we ever have an all-hands meeting with just white male speakers - we believe in diverse, collaborative views (whether it's skin color, levels, or experiences) that define and shape our projects and goals. The fact that most of us do it with the utmost respect and thoughtfulness with one another is contagious and empowering. 3. On a superficial but important level, I do enjoy the benefits here too. Being able to spend up to $150/month on anything athletic-related (pick-up b-ball game gym usage? Krav Maga classes? Marathon registration? It's all good!) is awesome.

Cons

1. There is a minority of vocal people that can be considered entitled and whiny. Our company culture attracts the nicest people I've ever met but I think we're too nice sometimes. Clarity is kind, so calling these people out for such pointless/wasteful behavior is a good thing. Okay, that's probably more on me to do that. I guess i'm too nice too haha 2. This is very superficial - but our HQ elevators seem to be too slow (or one is always broken). My health thanks you for prompting me to walk up several flights of stairs everyday because I lack the patience to wait.

Pros

The people and benefits here are amazing! Brand new office in Denver is something else. Growing company and many growing teams. Lots of opportunity ahead!

Cons

Typical growing pains that come with most start ups. Start in one direction, quickly pivot in another. Not really a con just something to be cognizant of.
