I visited Atlassian's Sydney office. There was a sign on the fridge in the kitchen attached to a function space that had 'guidelines you've had too much to drink' Included on the list was 'if you're slurring your words, you've had too much to drink' as well as 'if you've started making unwanted advances towards colleagues, you've had too much to drink'. The fact that 1) They had a sign telling you not to sexually harass your coworkers 2) It happened so often that they NEEDED TO PUT UP A SIGN telling people not to do it any more

made me decide I probably didn't want to work there. (This was 2015, maybe things have gotten better?)

Go on...

20% time that people use. Quarterly hackathons that the whole company partakes in. Healthy budget for travel, classes and conferences. Engineers have lots of weight on product decisions and ideas. Cloud teams use modern tech stacks and are doing cool things with infra/AWS. Founders are highly technical and still like to be involved in some high level technical decisions.

Are the hackathons during work hours? Maybe that's how they get some of that 20% time back :)
