      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.

      Pros

      Innovative product Incredible team across organization - smart, dedicated, energized, fun Empathetic organization Overall Slack is a wonderful place to work, and I have absolutely loved my time here.

      Cons

      Growing organization that is still finding its way from smaller start-up to now a 2K+ public organization. Sometimes processes can be overly tedious, and can feel like there can be too much of a big company mentality, when we still have the ability to be nimble if we could focus on that.

      World Class Culture and Team

      Pros

      Transparent leadership whose bottom line is _not_ to make a profit. I attribute a lot of the culture to Stewart. He is clearly very invested in social good initiatives (way before the pandemic started). For example, bringing in speakers to talk about racial justice initiatives, the last mile program, partnering with code2040, etc. The great part is that this culture attracts the best people! Folks that are incredibly kind and exemplify all of our values. Not only that, most if not all of the engineers are amazing technically. Technical leaders are very knowledgable and really level up their teams if not the entire org. There are also lots of opportunities to work on technical challenges.

      Cons

      The legacy codebase can be hard to work in sometimes, but it's getting better. The concentration of people of color and LGBTQ folks is not equal. Some teams are very diverse while others are not as much. The stock price is quite volatile, but trending upwards. We use Hack which no one really uses besides Facebook. Hard to find something as good for next job.
