Pros

- The people are not only talented, but among the most thoughtful, inquisitive, and kind I've had the privilege of working with - There's True Belief in the product and its ability to change the way people work, backed up by customer testimonials - A support-focused culture that takes joy in delighting people in small ways: responding to tweets with a bug fix ready, a topical gif, etc. - Clever, pragmatic executives that are engaged and understand the product deeply - One of the most racially diverse tech companies in San Francisco; very liberal, with a social justice bent - Very little churn at the employee and executive levels

Cons

- In its race to become a Serious Enterprise Business, it's starting to lose some of the whimsy and quirkiness that got it to where it is. - Those acclimated to a data-driven, CS Fundamentals Engineering culture will find things a little lax here; pragmatism is the law of the land and some shortcuts have been taken. - Ratio of junior to senior engineers is higher here than elsewhere, resulting in ample stress for the senior engineers as they try to manage technical debt. For the juniors, the result is fewer opportunities for mentorship and a feeling of floundering without a life vest. - The "no whiteboards" interview policy is great, but sometimes translates to a "no technical challenges" interview depending on the panel, and that can (and has) lowered the bar.

Pros

I love Slack's focus on people. This manifests both in the focus we place on our customers - taking customer service really seriously, responding to every tweet, focusing on building delightful experiences - but also in how we treat each other as employees and coworkers. There is a level of respect and courtesy that is really special and leads to a really inclusive and supportive working environment. I also appreciate the balance that Slack provides. It's an enterprise software company that has a deep focus on building a human experience. It's a start up that values work life balance. We're passionate about what we're doing, but also realistic and levelheaded.

Cons

There are downsides to working at startups, but with that comes the opportunity to build something from the start.
