While I found the multiple choice questions helpful, if you have never worked for the government before, many of the questions are impossible to answer truthfully ("Have you ever designed a cross-agency presentation?" "I am comfortable presenting to administration officials."). How do you answer? Yes - if you've done presentations to other top managers or across departments in a big company? Or No - because that won't directly match up with what's on your resume?
If the government wants to bring in the "best and brightest," people with private sector experience, that's a definite area in need of improvement or clarification.
