Yes, asking simple questions like this takes about 15 minutes and will weed out 98% of bad hires. I wish more companies would do this. Years ago when I would interview people for Delphi positions, the first question would be:

Instantly weeded out 98%. Really what you are looking for is work ethic. If I pay you will you work hard. That can't really be determined in an interview.
