Pros

Culture encourages people to naturally be themselves, it stopped being classified as work for me a long time ago and more of a place my brain goes to think about people collaborate. Work life balance is not just talked about but demonstrated here. Work hard and go home was painted on the wall of my office and it's respected and adhered to. I had a life event and my manager simply said, "go and do what you need to do, your family comes first".

Cons

It is a big responsibility to handle the collaboration of the size of customers we have, it is not necessary a negative but something to remember from time to time.

Pros

Overall, Slack has a good set of co-workers within Engineering. The product is decent, and contributes to helping people get work done as opposed to just making money off of ads.

Cons

There is no company direction. The product is stagnant, and the focus is primarily on getting more users as opposed to making a better product. No one, either in engineering or product management, can make a long term roadmap. We move from the crisis of today to the crisis of tomorrow. We constantly spread ourselves too thin.

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.
