I personally have never met (in person or on video) anyone that lived through (as a war prisoner) the Nazi regime. I've read stories and seen narrated short videos, but never actually heard an interview with someone.
The video below is an actual interview with Simone Arnold, a woman who was 12 years old at the time of Nazi occupation of Eastern France.
If you read the write-up underneath the Youtube site, there is much more information on this. It was produced with the help of the USC Shoah Foundation Institute founded by Steven Spielburg. A copy of the video is also on a private site.
