Pros

* Good work/life balance. Management seems to career about employees' wellness. Lots of fringe benefits including good Mat/Pat leave. * Company has a good name and is on a good trajectory. * Coworkers are pretty nice and mature.

Cons

* At least within Analytics, ICs are rarely promoted. Mid-managers come up with rubrics for judging advancement, but use vague definitions to make assessment fit their view. In two years, among fifteen colleagues, I've observed perhaps three IC promotions (manager class seems to promote itself) * In same vein, mid-management is reluctant to promote ICs to management, tend to hire from outside so nearly impossible to move up from IC to mgr * Fast growth issues: getting things out the door is focused on, so quick wins are praised and rewarded, while building scalable solutions is often overlooked. Result is a lot of tech debt and even basic data questions still take a long time to get answered. On an org level, code base is a behemoth and we've now finally been forced into clean-up mode because it's struggling to scale.

Pros

• Slack does Customer Experience right! We have a lot of freedom to do what is best for our users. This is a gem in the world of Customer Experience. • Great team and atmosphere, I work with a great lot of people, everyone's giving it 100%. • High-profile company, the product is amazing, and the benefits are very competitive.

Cons

• Don't be fooled by the no-blame, no-ego, we're-all-in-this-together approach. There is politics, like everywhere else. • The people at the very top of Customer Experience are control freaks. Their baby is growing up and they're having a hard time letting to. They are not receptive to disagreement, they get involved at a level they should not be and consistently undermine our managers. They don't know how to manage more structured organisation (or people it seems) and it can get messy and confusing.
