Pros

- culture is second to none - my manager is amazingly competent, helpful, fun - and I’ve had terrible experiences with previous managers - the product is by far the best one I’ve worked with in my 5 years of professional experiences - the tone of all meetings are fun and not like the normal robot drone tone I’ve become accustomed to in previous companies - good salary and benefits - Salesforce acquisition opened up our total addressable market

Cons

- Salesforce “harmonization” still in process (ie 2 different Okta’s, Highspots just merged) - Salesforce AE’s don’t really know what we do yet because SF didn’t set up/ use Slack well, which makes it hard to break into their pipeline - overwhelming with all the Slack channels and so much content (but also a good thing)

Pros

The people here are genuinely nice and caring. People do try to do the right thing in general and are dedicated to their jobs. The work-life balance is great, especially in the post-covid world, and I think people are really good at working remotely here. Also, I want to point out that this is a big company, so the stuff in my "cons" column might be a departmental issue.

Cons

One of Slack's core values is "collaborative." However, the way managers measure performance encourages division and siloing. The only thing that will get you a promotion is being the "DRI" for an important project. Everyone works alone unless they're an associate SWE or they need something, and they do try to help each other because they're nice and caring, but the incentives are to pull separately, not together. Surprisingly, Slack apparently does not, or does not always, collect direct reports' feedback on management as part of their review process. Weird!
