I had an interview there where the manager asked me to leave my laptop behind and go for a walk. I was hesitant after hearing stories of Uber conducting electronic espionage against its competitors. They could easily bypass Macbook security with a USB device (I had heard of that on HN too) so I was very nervous to leave my laptop behind and noted its exact orientation and position on the table. Sure enough when I returned my laptop had changed both position and orientation, but only enough to tell if you had specifically memorized it. I could be paranoid. They could have simply moved things on the desk. But anyway, people who are paranoid like me are advised not to take their laptops into Uber interviews. They are capable of just about anything, or so thinks my now paranoid self.
