I once got asked to spin off an ec2 instance from an image provided by the company I applied to, and then answer certain questions about the dataset on that thing. I had to write actual code to obtain the answers. All that had to happen within 24 hours. Then there was an on-site interview where they asked questions about stuff like JVM garbage collector fine-tuning and such. That was the best interview I had, ever.
