Pros
If you are looking for a fast moving tech company that works with the best tech tools, hires amazing people, lets us do our work without micromanaging - Slack is it. Incredible company with a transformational vision. The leaders do what they say and live the values every day. Work 2 days in the office, and no one monitors. No need to come in at all if you dont want to. I want to come in because its fun, the offices are beautiful with views over Darling Harbour and a barista on-site. The onboarding training I received was the best I have ever seen. So thorough. You get to learn about Tableau, Mulesoft, Salesforce, Quip, Troops and form strong bonds with your Slack cohort. Lots of opportunity to learn from colleagues through Slack channels - from San Fran to New York, India, South East Asia. Global outlook.
Cons
There is a lot of information to learn. Its not a con, but just prepare to be dazzled.
