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.

Pros

People and culture has to be at the forefront. Slack has hired amazing people with abundance of different experiences and expertise. On top of that, we've hired some amazing people in general who are selfless and HYPER collaborative. It's amazing to see such a big team in CS all working in unity when it can be hard enough working with just one other person. Leadership has been one of the most impressive things to witness since joining Slack. Leaders at Slack do not just say thing to say things, in every instance, I've seen leadership lead by example. Very empathetic and compassionate leaders that sincerely care about your well being and go out of their way to assist you when you're down rather than tell you about it.

Cons

Personally, I haven't been able to see anything that I can label as a con. If you're used to being in a startup and want things to move fast within a small team? Then perhaps this isn't necessarily that anymore. But at the same time if you're coming from a huge organization with 10s of thousands of employees? Things aren't structured to that point either. For me, it's a happy medium, but this could differ on what your expectations are.

Pros

Slack has a great emphasis on career and skill development, work life balance, and diversity. As an employee, you genuinely feel cared for and listened to, whether it's through Town Halls, executive channels, or the multiple surveys sent out throughout the year. The core values - empathy, craftsmanship, and humility (to just name a few!) are the basis for everything at Slack, from the way the product is built, to the way every team operates. Outside of the amazing culture, the benefits are excellent, and I can only see Slack continuing to move up and to the right in the upcoming years!

Cons

Managers can change quite frequently, as people are often being promoted up within the organization.
