What Is a Security Clearance Interview?
The interview is part of the background investigation for individuals applying for a clearance level that gives them access to sensitive information.
When Do Interviews Happen?
- Usually for Secret or Top Secret clearance levels

The interview is conducted by a background investigator either in-person or via secure video call.

Interviewers are trained to assess:
- Your honesty and consistency
- Potential security risks
- Financial and personal stability
- Foreign connections or influences
- Criminal or drug history
They cross-check your responses with what you submitted in your SF-86.
