Pros

Truly incredible opportunity - there are few companies that are growing so quickly, with roles expanding so rapidly along with hefty scope and responsibility for almost anyone who wants to claim it. Many people now at Slack, and still being hired into Slack, are the first ones to do their particular roles so there is an opportunity to shape and build from the ground up. This is not a place for people who want to "rinse and repeat". It's a place to solve hard challenges, do things for the first time, and set a precedent going forward. Slack is a career making opportunity and people on the team know that - it's full of smart people who are energized and motivated to do great work, together. As a marketer it's also refreshing to work at a tech company that truly values marketing and provides the budget, headcount, and resources to do the job.

Cons

We're still figuring things out and that can be painful. Processes can be clunky and difficult, our systems and tools and data haven't kept up with our growth which can impeded the ability to get work done. There are competing priorities and while everyone generally has good intentions, projects can get bogged down in bottlenecks throughout the org. We don't have a history of "the way we do things" which makes work more exciting but also more chaotic - we are not yet the efficient machine we'd like to be.

Pros

As a marketer, I can't think of a place I would rather be. Having a passionate user base is incredibly rare, especially in b2b marketing. We're still early days and there's still so much opportunity to make an impact. You have an opportunity to define and build out programs for the first time. You get to work with a talented team of good people. Great work-life balance, benefits, and norms. Leadership cares about the team. You'll frequently hear Stewart say what keeps him up at night is the people and ensuring the wheels don't fall off. Yes we've faced growing pains, but some of the reviews posted here are not representative of most peoples' experiences. Amazing, inspiring new HQ that encourages creativity.

Cons

Growing the team >2x each year has led to some pain. We've hired some people who aren't a fit but we've also hired a lot of great people. Additionally, growth of some teams has far outpaced that of others, leading to some teams being incredibly strapped while others are blocked on work. There are still major gaps in many teams/departments while some roles are starting to overlap.

Pros

Slack's product and culture (outside of Salesforce influence) is second-to-none. The positive reception and enthusiasm end-users have for the product is super encouraging to see as an employee. After the Salesforce acquisition and Co-Founder/CEO Stewart Butterfield's departure, new CEO Lidiane Jones took the reigns, and she has exceeded my expectations for Stewart's replacement. She recognizes the unique value Slack & its culture brings to the table and seems to work to protect it.

Cons

Upon full integration post-acquisition by Salesforce, automated processes and tools that employees were accustomed to (and built as a result of our value prop/company outlook of automating any processes possible to increase efficiency and productivity) were replaced by old, antiquated tools and processes. I can no longer to the job I used to do. There's a lot of attrition and morale is low; leadership is also being replaced by old-guard Salesforce leaders.
