Pros

Plenty of opportunity for growth. Leadership is close to the work, personable, and very human. Response to changes in the world are positive. Understanding of family needs, and monthly Friday company holiday have been nice.

Cons

Most people seem overworked. Political views and opinions find their way into conversations and internal comms often with strong liberal leanings, lending itself for an uncomfortable environment for conservatives, and libertarians. Alternative opinions get shut down with no consequence.

Pros

- The best people, and a really healthy culture - even working remotely, you will feel included and engaged - Work with an amazing product that really impacts people's working lives - Really walk the talk when it comes to social justice and diversity - Tons of opportunity to take initiative, and learn/grow outside of your role - Best perks/benefits around

Cons

- This isn't really a negative, but Slack is a fast-paced, rapidly changing environment. To be successful here, you must be able to weather uncertainty. Despite this, you will be well supported.
