Pros

Decent opportunities for growth. Working hours flexibility. Relaxed environment and fantastic colleagues. Versatile position — definitely not a call centre kind of job if that's what you're imagining.

Cons

Californian PC culture can be a bit too strong.

Pros

-Extremely smart teammates. -The best culture I've experienced at a technology company. People genuinely want to be successful together, super collaborative culture with an intentional approach to promoting and maintaining our cultural values. -The business opportunity is massive and we've only just scratched the surface. -No shortage of opportunity, in any role. Execs are open to feedback and great listeners. If you're willing to do the work, you can have a strategic impact. -Pay is competitive, benefits are the best I've ever had and the office(s) are incredibly nice. -People seem to genuinely enjoy their jobs. -This is a once in a lifetime career opportunity.

Cons

-Moving faster than any software company in history - this means that things need to happen quickly. -Change can be uncomfortable if you're not used to it. Exec team is aware and focused on maintaining a positive culture. -It's not a cushy job, the opportunity is in the impact and REAL work you'll be doing as the company continues to grow.

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.
