For renewal most people do not need an interview. If you have been selected for an interview it is typically because something in your renewal application has triggered it - usually on of the countries you have listed in your travel history over the last 5 years. I suspect in my case it was the inclusion of Cuba that promoted an interview.

There is no winning involved, and the interview is usually pretty straight foreword part of the renewal process. If you find this all too much trouble, just let GE lapse and go back to using the normal lines.
