It's a nasty sounding word to match a nasty practice. While I am about to make fun of it, that is within the context of the Star Wars universe. I support the work of Amnesty International and you should too.
There is another type of interrogation that I regularly do as part of my work and that is requirements gathering for business information systems. There are a lot of similarities. I ask a lot of questions and my client is often not free with answers. I'm certain some of my clients think it is torture too. Hopefully that is not because of how I do it... It is a necessary process but it shouldn't be adversarial nor does it need to be.
Preparation is key. Make sure you have a clear idea of where you are at now and have it documented clearly before calling the consultant. That will reduce the pain for everyone.
So now our heroes are on the way to Alderaan while Princess Leia gets the VIP treatment from her own dad and his interrogation droid assistant... Harsh.
