Elizabeth Warren is already a prominent figure at this point in her career, but isn't as overtly political as she perhaps is today. The talk is very candid, and she goes into her experiences growing up, her somewhat roundabout education, her early days as a solo law practitioner, and how she began her research into bankruptcy law. Perhaps the most amazing thing about this interview is that it was conducted before the start of the Lesser Depression, and how prescient her views are given what's taken place since.
Regarding the interviewer, the Institute for International Studies at Berkeley has been conducting this series for more than 25 years, and Harry Kreisler does a great job of moderating the interviews. I've watched a set, and they're quite something. All are available on YouTube, from Abdullahi Ahmed An-Na'im to Howard Zinn.
