I Pinch Myself Everyday!

Pros

The culture at Slack is unreal. I've never been with a company that treats their employees with this much respect & admiration. They truly care. Truly. I pinch myself every day with how lucky & blessed I am to work for a company like Slack. Stewart is such an amazing servant leader. I respect him & his dedication to the wellbeing of his employees & the health of this company. I really enjoy being apart of the Sales & CS team. They are very supportive & encourage opportunities to lead within the team & through different company initiatives & programs. There are vast opportunities to explore different & parallel career paths within the company. The D&I program is also one of the best I've been apart of. I am inspired every day by my fellow colleagues.

Cons

Slack operates within a "start-up" atmosphere at times and there are growing pains that are very understandable. There are opportunities now that management is taking to improve their D&I hiring & promoting initiatives from folks entering Slack as an intern all the way to C-level executives. I am happy to report that due to Slack's open & collaborative culture, I admire their honesty with any of the growing pains that come along & Slack's invested interest to constantly improve, grow & evolve.
