Pros

-I've never sold a product (let alone an enterprise software) that had so much customer love. When I tell people I work at Slack or meet people at conferences, I'm met with so much enthusiasm about the product. We really have the power to transform people's working lives. -Company has had an amazing trajectory and still has so much untapped opportunity. -Lots of smart people work here. -Great work life balance. -Great benefits and perks.

Cons

-Tendency to hire people from other tech companies which leads to lack of diversity in experience/backgrounds -Company grew extremely quickly so now there's a fair share of growing pains (decisions made too quickly without sufficient data, managers get promoted internally and may not have relevant experience, etc)

Pros

I've been at Slack for 9 months and I'm really enjoying my job. They hire top quality people and they try to live the values - smart, humble, hardworking and collaborative. People are appreciated for the work they do and it's possible to have a large impact on the company.

Cons

Lots of change - I've had 3 bosses in 9 months. Hasn't had much of an impact on my day to day life, but it's a bit thrash-y. The way we use Slack can be overwhelming - I must be in 100 channels. I look forward to the day when are priorities are to make the product easier to use for Slack-centric companies. Sometimes the best way to get more work done is to turn off Slack.

Pros

- Mature, professional, smart and genuinely friendly people - No tech company BS - we get our own lunches like adults, and we enjoy the company Gather Hour and 1/week lunch and breakfast as a time to connect with people across the company. If you are looking for free food (other than the awesome snacks), this isn't for you - No pets - again, aligns with the "work hard and go home" motto. - Amazing baristas on multiple floors - this one can spoil you rotten - The company has experienced, smart leaders in product, sales, comms, engineering etc who are very down-to-earth and approachable

Cons

- As I've seen other reviews mention, a lot of systems and data are really difficult to access or use. If you joined in the last 1-2 years (as so many have), you probably don't know where to find it. - Growing pains with processes, such as OKR processes that are rolled out without much direction on how to measure results consistently across teams! - If you are considering any role on the marketing team, think 10 times. That team has been rudderless and with many conflicting visions for too long. Even with a brand new CMO, things are going to take a *long* time to come around. There is a lot of politics, as people who were hired in leadership positions were hired when the company wanted SMB/consumer backgrounds. Most are less qualified for the company's current vision and enterprise focus. I think that team has had 2-3 re-orgs and team changes in the last 1 year. They just announced a big re-org and some good people are gone. The team and functions are so fragmented it's difficult to get any projects done smoothly if marketing is involved. Marketing leaders quite aware of these problems but it's clear they are more focused on what their roles are going to be in the new org rather than solving them. The relationship with sales has improved but marketing is still far from being a great (much less equal) partner to sales, product management, and other teams.
