Pros

- The best people, and a really healthy culture - even working remotely, you will feel included and engaged - Work with an amazing product that really impacts people's working lives - Really walk the talk when it comes to social justice and diversity - Tons of opportunity to take initiative, and learn/grow outside of your role - Best perks/benefits around

Cons

- This isn't really a negative, but Slack is a fast-paced, rapidly changing environment. To be successful here, you must be able to weather uncertainty. Despite this, you will be well supported.

Pros

- Very transparent company. - Lot's of opportunities to learn and grow within different areas of the company. - Management is very supportive and want you to succeed. - Outstanding personal/ entertainment perks along with professional development funds and opportunities. - Lots of remote roles. You can leverage working from home and still be in/ work towards a role that is offered in a different country, region, etc.

Cons

Not many... Due to covid, working from the office is not a possibility at the moment. Miss the team lunches, and events :(

Thanks for leaving a review. It makes us really happy to hear that you feel you have plenty of opportunity to learn and grow here at Slack, and that you feel supported in a transparent environment. We miss having our employees in the office too - we appreciate your flexibility as we learn to adapt in these uncertain times. -Slack

Best People I've Ever Worked With

Pros

-The strongest sense of team and collaboration I've experienced anywhere I've worked. Slack culture is built on helping others and it makes the work easier and more enjoyable. -The company is growing so quickly there are always new problems to solve, new opportunities to take, new ways to stretch yourself and learn new things. -Slack has a customer-centric culture and that is a wonderful thing, especially for those of us on the Customer Experience team. We are seen as a value-add, not a cost center.

Cons

-The strong culture of collaboration can make it hard to unplug. There is always more to do and more colleagues you could help. -The product and company are changing constantly and quickly. If you don't love a new challenge literally every day, and having to learn/re-learn how things work this might not be a good fit. .

Thank you for taking the time to share your thoughts! It is so wonderful to hear that you see strong team collaboration and feel surrounded by continuous opportunity to learn and grow. We hear you, sometimes it can be difficult to unplug--we encourage you to take advantage of PTO and our monthly company Fri-yays to really relax and recharge! -Slack
