Pros

- Good work/life balance - A reasonably interesting product with its own set of challenges - Beautiful offices in many different countries - Quality of design matters

Cons

- Easy to hide in the organizational shadows and do very little work - Over-sensitive culture infused with strong 'woke left' narratives and not afraid to push it in your face! - Status quo management and development culture.. repeat that week's popular phrase as stated by executives and you'll do well - Heavy in the management layers - Inappropriate leveling criteria for engineers, leading to low technical competence

Pros

Management really cares about you. You'll work with the smartest people you have in your career and you will work in a fast-paced space with an incredible opportunity.

Cons

The only real knock I have on Slack is being an employee in a non-SF office. The world seems to revolve around SF and it can feel like if you're not in that bubble you are lost in terms of recognition and more importantly career opportunity. I think this is something being addressed and feedback that is heard but as of right now this is still a sore spot for me.

Pros

Amazing company! So happy I ended up working for Slack. Such a nice culture and environment to work in, were people genuinely live the values and they are truly embedded in the company- empathy, craftsmanship, courtesy, solidarity thriving and playfulness. Management is superb, super talented and a very transparent organization. Got the chance to meet many of upper management including co-founders during my training at HQ in San Francisco and they are very nice, approachable and extremely talented. I can't imagine working under a better CEO than Stewart. Such an interesting time to be at Slack; growing quickly, great product and interesting market. Highly recommend Slack! Great benefits including professional and personal development, also additional benefits covering phone, commuting and fitness expenses.

Cons

I've not experienced any so far (I've only been at Slack a few months)
