Pros

The NICEST, most thoughtful company culture I've ever experienced. I have not met a jerk yet and bullying / fear-inducing is NOT tolerated here. It's amazing to feel safe, considered, and heard here. The benefits are amazing - all monthly medical premiums are covered for the employee and family. The annual personal development ($500)and professional development ($2,000) funds are compelling. Slack's mission in making work simpler, more productive, and more pleasant truly resonates internally and externally - and I see so many positive reactions from within and from our customers. It's truly what we are built for and it keeps the morale, quality of product, and culture thriving.

Cons

The NICEST, most thoughtful company culture I've ever experienced. Yes, our biggest strength can be our biggest weakness. Sometimes, crucial conversations can be difficult when we are too focused on being nice than simply telling what the problem and solution is. But honestly, this is the biggest problem I've encountered so far and I'll take that over any other company.

Pros

• Most work/life balanced company I've ever seen • Great pay and benefits • Genuinely listens to input from entire staff base • Great colleagues • Strong sense of teams getting to own their decisions (this was more difficult in the past) • Decisions are made transparently, and execs can be publicly asked questions with and will publically answer thoughtfully and thoroughly. • Building a product customers actually like and pay for directly feels genuinely good.

Cons

• Currently not a lot of room for growth in the Design org (though this is actively changing) • Working outside of HQ (SF) can be challenging for the remote employees

Pros

-Culture, inclusive and feel like you have a voice that is heard -Slack is a sexy product, people LOVE using it and rely on it, plus the reputation we have out in the community is solid -No shortage of new things to build out process wise, projects to work, so many cool things you can do; you leave your workday feeling your impact on the company with the work you did. -Leadership; Stewart is SO awesome, he hangs out during gather hour or lunch sometimes and he chats with everyone and anyone, he is relatable, humble, and smart. He makes you feel excited to be here and be a part of what is in store for our future as a company. Slack has a heart and if you come here you will understand why people come to work here. It's nice to be somewhere where you feel the company aligns with your own personal beliefs too. -The future is BRIGHT, everyone who works here sincerely believes in this product and what else could happen with it - everyone who works here WANTS to be here.

Cons

-Same with one of the pros' - no shortage of work to do, so just pace yourself and do one thing at a time. -Growing fast, keeping the culture strong as we scale so fast
