Ok this is my experience with the USSS after 11 months of the application process and two polygraph examinations. My first exam was in Nov and lasted about 5 1/2 hours.  The format of the exam was as follows:

- Pre-poly briefing (going over my application and the   
  questions that would be on the exam.)
- Stim test (the numbers game)
- The exam had 4 areas of questions:
     - Terrorism questions(security questions)
     - Integrity questions (control questions)
     - Drug usage questions
     - Criminal activity questions
- The exam was boken into two sections
     - securtiy and integrity
     - drug, criminal and integrity (b/c I was having problems 
      with the integrity questions of course.  So they had to 
      do it again.
- There were about 8-10 questions asked each round and 
   they asked them 4 times in one setting before I was taken   
   off of the poly.
- During the 1st poly I was asked the 1st round on 4 or 5 
  seperate occassions b/c my integrity questions were giving 
  me trouble.
- During the 1st poly I was asked the 2nd round (Drug and 
  Crime just one round.)
- Post test interview
    - I come back in the poly room after about 20 min. and was told that I failed the drug question and that he wanted to help me as much as possible, if he didn't he wouldn't have spent 5 1/2 with me. (yea right)  He was very professional the whole time but insisted that there was something in my back ground I haven't told.  I informed the interviewing SA during my initial interview that I had been high before but never smoked Maj.  He said if I had been high then I had used Maj.  and asked me to change my application.  So I did.  I thought the whole prosses was over for me and ring....ring... ring...it was an examiner from HQ who wanted to administer a 2nd poly to ensure that that one time use was all.  So he comes the second exam.  I must mention here that I had no other trouble on my 1st exam except with integrity questions.

2nd exam.

- same as 1st for pre-poly, asked me to rank my self in integrity and honesty from 1-10 and gave me the honesty speach.

-the questions were Drug, crime and integrity and one security question (have you been truthful on your application)

-at each setting 4 rounds of 8-10 questions and there were three settings.

- the last setting however he only asked me about 6 questions none of them were control questions, they were all relevant.  I am 100% sure of this.

-  Post interview after 15 min after last round.

He told me I had a problem with the application questions ( have you been truthful on your application) I admitted nothing as there was nothing to admitt to.

I called USSS personell office Friday just to be informed that I would be recieving a letter in a couple of weeks that will let me know where I stand in the application process.

This means that I am out, this letter is a DQ letter.  For any of those who are going through the process, after the poly is the BI, in which you do not recieve a letter but instead a phone call requiring you to come in for a urine test.

This is my experience, though I will be DQ'd never did any of the examiners act in an unprofessional manner.  I wish I could say they did b/c I am out of 11 months of time expenses and a life long dream, and possibly out of other SA jobs b/c of the poly.
