Pros

I have never seen a company so dedicated to its values. I know, I know, every company has a list of values and principles and claims to live by them blah, blah. But at Slack, it isn’t really any list of values, so much as it is an implied way of being. If you are collaborative, respectful, put team first, find creative solutions, the. You will be more successful here. In some cultures, that simply isn’t true - over time you get sucked into the grimy, political necessities. I have seen it, fallen victim to it, and I am never going back. Working at Slack, I feel liberated to to my best work. Stuart is amazing. The hype is real. Finally, I work in Sales, which is often the most competitive dog-eat-dog side of a company. Not here. We win together or we don’t win at all. I know it sounds crazy, but come see for yourself.

Cons

Typical growth challenges. We use Slack for EVERYTHING at work and once in a while, there is a better way to get something done.

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

* Competitive Compensation & Benefits * Thorough interview process * Possibility for collaboration across teams / departments * Heavy use of Slack at Slack!

Cons

* Values are not lived, inclusion and diversity are mostly buzzwords without consideration of the real lived experience of minority groups or what true inclusion might look like * Strong internal censorship, messaging closely watched and criticised if seen as inappropriate or not towing the party-line * Focus on external image overwrites focus on wellbeing of employees at times * Very limited career opportunities in EMEA, centralised decision making from the US which impacts growth and opportunities in EMEA * New employees are specifically asked to provide Glassdoor reviews.
