Pros

The people at Slack are bright, driven and amazingly kind. I have only been with Slack a few months, but instantly felt part of the team and can clearly see where I can add value to the organization.

Cons

The down side of being so nice, is that sometime people have a hard time giving critical feedback, but the good news is they recognize this and are working to improve leadership and IC skills around this. The other thing we need to do better as a company is enable our customers better. I used Slack before joining Slack, but had no idea I was only using 5% of it's capabilities. Now that I am here I can't imagine working without Slack as a central part of how I do my job and we have to show this to our customers.

Pros

An amazing opportunity to build the foundation of how work gets done in the future. Working at Slack is a complete paradigm shift that I couldn’t have imagined prior to starting here. I don’t know how I’d ever work at a company that uses email again. There is tremendous career opportunity.

Cons

Not for those who lack resilience, struggle with ambiguity, need roles/priorities spelled out to them or who are looking to ‘coast’.

Pros

Slack operates like a start-up in many ways. You can have impact, make changes without bureaucracy, and work in a fast-paced environment. At the same time, Slack has the stability and work/life balance of a bigger company. I've been able to learn a ton during my time here.

Cons

We are definitely still figuring things out and building. Things are often ambiguous, and part of the fun is figuring out how to operate in ambiguous situations.
