There are some smart and friendly people in supporting roles at Slack

Cons

Pros

Good product roadmap, positive future as a product. Slack is for sure the way of the future. Goodbye email.

Cons

Very homogeneous and minorities do not thrive in this environment. The HR team has no support nothing really set up to help underrepresented minorities be successful in this environment. No education around cultural or communication styles and no resources on biases or true bias trainings except for the usual "unconscious bias" jargon. POCs will very quickly become isolated and it's up to them to make others around them feel comfortable or else they will be sacrificed. I have watched this happen to POCs. Especially Black Women.

Pros

+ Work life balance is real + Incredible values - the first 300 or so people hired are incredible people who genuinely care about making the world a better place and are fiercely passionate about the product and each other + Relatively diverse + Very customer- and employee-centric + Smartest people I've ever worked with and some of the most humble as well + Exceptional learning & development opportunities + Great pay

Cons

- Whatever Stewart says goes. He has genius ideas and high standards (a good thing), but it leaves management with little autonomy and can cause slow downs/sudden changes in priorities. This may have gotten better as the company has grown. - A lot of people were really sad to see Bill Macaitis go. Very different values and POV came in with the new marketing lead. A lot of people have left since that transition. - Started out with the noble intent to hire authentic, empathic people who wanted to be part of a movement vs climb in their career. Those people are leaving or getting pushed out and more traditional enterprise B2B folk are taking their place. - Not accepting of politically conservative people. Even centrist left-wingers can feel uncomfortable there.

Thank you so much for your feedback, it’s incredibly valuable to us. As you can imagine, a company will look very different at 50 employees compared to 500 or 1,000 employees. Regardless of company size, focusing on hiring great people and listening to everyone’s perspectives is and always will be a top priority for our leadership team. One thing we are learning as we scale is that there will be different iterations of our business needs and culture which may not continue to be the best fit for everyone. We appreciate your candidness with regard to your personal experience at Slack. Thank you again for sharing.
