Applied for a summer intern position in late October/early November of the preceding year through USAJobs.gov. Got a call from the office's Director in mid-December offering me a position as an Intern--no interview. Position required a security clearance, so I submitted the necessary paperwork (a 30-page form documenting previous residences, international travel, criminal activity, drug use, financial troubles, etc.) in mid-January. Was interviewed by an investigator regarding that paperwork in mid-March. That interview lasted about 30-45 minutes and served to confirm/clarify the details on the form. Was granted security clearance by late April to start internship in late May.
