@waldowaldo All my interviews have went like this - First, they are going to go over your answers on your SF-85p. After that is complete, the investigator will “confront” you with any derogatory information that they developed prior to the interview. For example - late payments, credit problems, bankruptcy, criminal charges or convictions, job terminations, etc.
So @datesnotrecalled is correct in saying that the form is the beginning of the conversation. However, I do know that contract investigators are bound by company policy with respect to interview etiquette and protocol. Meaning they have to adhere to a specific guideline and script, so to speak, of questions. They cant just arbitrarily come up with their own random questions they want to ask subjects. I recommend recording the entire encounter with the BI - check your states laws regarding 1 party or 2 party consent!
Regarding the drug use question - you are correct the sf-85p only asks for use within 1 year; however, if you also filled out the sf-85ps that form asks more broad and specific questions regarding drug use. If you want my advice - don’t volunteer anything that they won’t or can’t find out.
And finally, with respect to references being contacted - all they have ever done on my investigations is send out questionnaires to references that I have listed.
For what it’s worth - when I was a state LEO, the background investigations on regular police officers were much more intense and intrusive than the federal governments tier 2 or tier 3 product. To be honest, I wouldn’t even consider the tier 2 or tier 3 a legitimate background investigation when comparing it to what a regular municipal, city, county or state cop goes through to obtain employment.
