Pros

Slack has a beautiful office in SF which is one of the most wonderful offices I have worked at Aesthetically. Good Co-workers who are nice and work together collaboratively

Cons

Everything else especially Management. The Management is very traditional, and has low diversity although Slack stresses on being a very diverse culture and tries to portray this via Social Media or Articles however internally that's not very true. There are no Managers who I can relate to who, like other Unicorn startups are less traditional, new generation, energetic and diverse. I also wish we had a more Front End specific Managers because most Managers here are not very good at Front End Engineering which causes discussion gaps between Engineers and Managers.

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.
