Pros

Wonderful culture: humility, empathy and just plain good natured personalities abound. Having worked at many large, high profile internet companies the hardest thing to get used to is .. Yes, these people are also very very smart and talented

Cons

Slack is essentially selling *reliability* as it's main feature, and when it comes to scalability problems, reliability is the least fun (compared to fast, big and kinda reliable i've had at other places) .

Pros

Working alongside of the most grounded and supportive team members you'll find in the tech industry. Great benefits - free healthcare, generous mat/pat leave, personal development and professional development funds. Culture is friendly and the offices are beautiful

Cons

Constant change can sometimes be hard to keep up with. Teams shift around a lot and sometimes there is a lot of ambiguity. PTO is only 20 days instead of unlimited
