I'm not sure of the level of intensity you believe Uber or any company for that matter except a defense contractor would apply to the screening of prospective employees, but I suspect you'd be disappointed to know the truth.  In the absence of a criminal record (which I don't think he had) there'd be no reason to bar him from employment.  

And as for Home Depot, surely you jest.  The only thing that HD checks for is whether you've bought something and whether you have a valid driver's license.  To do differently would subject all HD's customers to a ridiculous, unwarranted and costly vetting process, and that will never happen.
