Pros
Free food, free beer and whiskey. Great place to work if you want to get bombed on a regular basis. Also, if you are a white male, this is really the place for you, especially if you miss that fraternity culture of people who "get you" (wink, wink) and understand how to kid around. You will love it here!
Cons
See all the five-star reviews starting from about nine months ago? Want to know why? Someone noticed, "Oh my gosh, we are getting bad reviews on glassdoor.com" and decided that something MUST BE DONE about this. So, that person, being an Atlassian True Believer wrote a blog and then everyone said, "We must fix this! I know, we'll all go online and write five star reviews!!" And then HR said, "I know, we can get on the bandwagon too, let's buy into the sponsored profile thing on Glassdoor so we can promote ourselves." And Mike and Scott sat back in their glass houses and said, "Whew, that's under control." And if you think I am making this up... I am not. If you want to join a cult and tow the party line, this is a great place to be.
