What are the typical questions a investigator will ask references during a background investigation? And what are employers generally asked?
For an MBI your references and employers will not be interviewed by an investigator, but rather OPM will send out a standard form letter for them to fill in asking general open ended questions about your, or your employment period and if they know of any adverse information about you concerning criminal conduct, drug or alcohol abuse, etc.....
This goes for SF85P background investigations?
Yes, for an MBI national security and public trust investigations are the same as far as interviews conducted.
