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

The company culture is the best. The people you will be working with and the ones you won't will treat you like family. There's a sense of ownership that I have never seen before

Cons

So far, everything has been positive
