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)

Pros

So many pros... a product that is truly innovative and making peoples working lives simpler, happier and more productive, fabulous office space, amazing food, massages... But, I am probably most impressed by how amazing the people are. Respect, courtesy, humbleness, collaboration, and great work ethic abound. I genuinely love coming in to work every day!

Cons

The timezone difference between Dublin and SF HQ (and other offices) can make connecting with our international colleagues quite challenging. But, generally there is a lot of understanding and flexibility surrounding this.
