Law enforcement pre-employment polygraph examinations typically have about a dozen questions, of which perhaps as many as four may actually be relevant. The relevant questions are fixed and are not dependent upon the examinee's answers to any pre-polygraph questionnaire. Where there may be some flexibility is in the choice of "control" questions presented to the examinee.

For examples of the kinds of questions typically asked in state and local pre-employment polygraph screening, see:
