Defense Media Activity interview questions

I applied online for a GS-1035-11/12 opening. I was referred and invited to interview. There was no pre-interview over the phone. I sat on the other side of a table and faced a 3-4 person panel that asked me questions related to the opening. I was also asked how I would react in two-three different scenarios, dealing with professional knowledge and ethical conduct. The interview lasted about 30 minutes.
