Pros
Free lunch Benefits Wacky t-shirts Australian accents Fun activities
Cons
The great south pacific cargo cult: Atlassian. A corporation trying its hardest to be an ersatz Google, both culturally and technically. Don't be fooled. The wacky t-shirts, hackathons, goofy hats, etc are a thin veneer over the rapidly declining cultural edifice. Prepare yourself for constant absurd politics, pointless territorial battles, and immature/ineffective management. The stateside brands (BitBucket and HipChat) represent small vanity projects on the fringes of the larger JIRA and Confluence empire. If you work on them you will be irrelevant. Additionally these two brands are 'also-rans' compared to the more prolific products in their respective sectors (GitHub and Slack) so you unfortunately don't even get any prestige or credibility.
