When it comes to hiring decisions if there are tied candidates but only one position it can often come down to candidates A was quiet and didn't ask any questions and seems disinterested, but candidate B had loads of questions to ask at the end and seemed really interested and keen and wanted to know x, y, and z.
Who do you think gets hired in those scenarios.
But yeah it is sometimes tempting to turn the tables :). So far no one has done it to me, but not sure what my response would be. "Haha nice joke! Ok we're outta time thanks for coming!" I guess!
