Pros
The company itself has some strong points, hence the 2 stars and not a 1 star rating. They have the kind of fun atmosphere you would expect from SF tech companies, beer in the kitchen and ping pong competitions at lunch, free lunches and paid volunteer opportunities.
Cons
But on the flip side, they lack a level of professionalism that one might hope for at any job. I don't mean the stuffy suit and tie feeling of large corporations or financial institutions, rather a sense of leadership and respect that helps careers to grow and smart talented people to stick around. I left because the particular team I was on had fired their manager and spent months in meetings that devolved into screaming and swearing on a regular basis to try and tackle the issue of how to handle the workload. There was no consensus on the correct approach and no strong leaders to step in and implement any judgement or experiential foresight. But in the time since I have left, I've known many others to also take the leap to new and exciting opportunities and each time, I have heard them talk of the bitterness of their departure in the same ways in which I felt when I left. Atlassian is just not the top company it portrays itself to be. Two thumbs down.
