Pros

I've worked for a lot of tech companies, and Slack is at the top of that list. All teams across all departments work well together, and are oriented towards the same goals. The credit for this goes to clear and thoughtful communication from leadership, and a complete lack of dysfunction or toxicity (as far as I can tell, anyway). Pre-shutdown, we had fantastic office culture and perks, but after going fully remote, the company figured out how to adjust and retain that culture, which is remarkable. The work we're doing feels valuable and meaningful.

Cons

I don't have any cons. I love working here.

Pros

Hard work, humility, integrity, kindness, respect, and transparency are so effectively and holistically enforced from the top down - working here makes you want to be the very best version of yourself (both professionally, and personally) that you can be. I have never felt so fulfilled by the work that I do! This is also a company that truly cares about its employees. You will never feel like just a cog in the wheel, which is really rare for large companies.

Cons

Things at Slack move FAST, so it can be easy to fall behind if you're not actively making it part of your daily workflow to keep up.

Pros

Leadership, work-life balance, culture, community

Cons

Everything you would expect working for a hyper-growth, recently-public company. Lots changing at all times both internally and externally but I have total trust in our team to bring us through any/ everything, which says a lot.
