We put together a placement test to help people find out what department they should work in. The questions ranged from amusing to disturbing, feeling more like a psych test than job application. Take the test for yourself here: https://deloscareers.com/placement
We also had a lot of fun with Westworld on social media.
Here's also some great OOH stuff we did that included vandalizing our own ads.
Watch the video of us graffitiing our ads outside of a tech conference in San Francisco.
