Pros
There are so many! Yes there are the cool things like great offices, treats like massages and great food. The real pros for me is that the quality of my working life has fundamentally changed. Gone are the days of battling through hundreds of emails before even starting the day. Communicating using Slack is, dare I say it, fun!! I feel truly valued here, it is such a high support environment. My team are amazing and we constantly help each other be better. One of the main things I noticed when I started at Slack was a complete lack of ego. People with big egos, or a 'look at me, I'm great' approach to working, aren't successful at Slack. We thrive on collaboration.
Cons
The only con for me is timezone, I would love to be able to have more real time with my North America and APAC colleagues, but everyone is very mindful of those challenges
