Agreed, I took notes after every interview (bombed on several in a row, like the OP), then collated common questions and prepared brief, positive, well-written answers. I went from failing every interview to acing every interview, many would say things like "that's the best answer we've heard" or "that's a very thoughtful response", well, I spent hours preparing them, unlike most other candidates! great thing about phone interviews is they won't know that you are reading from a script! Writing them and repeating them also helped me memorize them enough for in-person interviews. It also calms the nerves to feel so well prepared.
