Easy, it’s a government job. Be drug free, and not a brick. Other than that they don’t ask much, just elaborate on past experiences. Pretty basic interview process. Good luck! Really not that hard at all

Asked me questions about security requirements, and how would I access a problem if one were to arise. Dress for the part, slacks button up shirt nice shoes. Make eye contact with the person that was talking , listen to the questions carefully and restate then answer.
