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.

Pros

Culture encourages people to naturally be themselves, it stopped being classified as work for me a long time ago and more of a place my brain goes to think about people collaborate. Work life balance is not just talked about but demonstrated here. Work hard and go home was painted on the wall of my office and it's respected and adhered to. I had a life event and my manager simply said, "go and do what you need to do, your family comes first".

Cons

It is a big responsibility to handle the collaboration of the size of customers we have, it is not necessary a negative but something to remember from time to time.
