Did the interview a couple of weeks ago at LAX. Got checked in and waited 5 mins, and when called in, the officer asked me my full name, asked why I wanted to be in GE, and then she went on to talk about the benefits of the program while emphasising that if caught in a random check to be in violation, one gets thrown out of the program. The passport that I had applied ran out of pages before the interview, so I had a new one. She confirmed that and updated GE with the new one. All done in 10 mins.
