An interesting detail of President Elect Obama's vetting process is the questions. Here's a few of the 63. Should you ask these questions (or some variation of them) to your own job applicants?
“Briefly describe the most controversial matters you have been involved with during the course of your career”;
“Please list all aliases or ‘handles’ you have used to communicate on the Internet; include links to blog posts and links to your Facebook page";
The answers might be more interesting than their greatest weakness.
