Worst "hackathon" turned out to be the boss (scrum master type) and a Magento guy (super OCD) working on a tiny tiny adjustment to a email template. They didn't really do anything and expected me to just make it all way better with CSS alone. I built out a robust responsive email in a codepen for them. They acted like they couldn't trust me to be a part of the team because I wasn't contributing - but I wasn't even sure what was happening. Between gathering refreshments and patting themselves on the back... it was hard to see what they had done. The online presentation to the magento people was pretty funny to watch though. If you think you can't have a presentation about nothing - think again. Magento is totally fucked. The word 'hacking' is not really suited to describe 'programming websites/applications quickly' anyway. 'Ninja' and 'hack' should always be considered red flags. 'Magento' should be a triple red flag: Jerk-off Jesus-complex boss, self-centered out of touch programmers, crap product. Watch out!
