I've been given a test that was basically about showing a list of drivers on a map, updating positions, calculating closest driver based on the user position, etc. Very basic thing. Had 2 or 3 days to do it. I've seen other people here saying that they basically wanted you to work for free and never hire you, which is ridiculous. This is a typical hiring exercise, designed to measure your various skills. They threw my work away as soon as I passed that step.
