Pros
Great benefits and compensation, pockets of good people throughout the company.
Cons
Company values are more of a marketing tool than something actually lived by and put into practice. Management is a real concern, your experience at Atlassian depends entirely on the manager you get. Most toxic workplace I have ever worked in. The onboarding experience is down right awful, workplace bullying and toxicity starts on week one. You'll get yelled at, spoken down to, undermined, told 'that won't work here' and meet resistance at every turn until you give up like the rest of the employees. Few people at the company truly have experience at scale, as a result decisions take longer than working in public service and the quality of work is laughable. Success seems to be bound to how much you can talk about the work and self promotion, not enough people actually care to follow up and see if any work is actually being done. This is career suicide, there is no progression, no one really cares, it's a company full of people who 'rest and vest'. Performance is in the hands of management that simply can't be bothered to do their job. If you go to HR or speak up about any concerns, expect immediate retaliation from your manager.
