do they actually ever 'keep your cv on record' ?
I can only base this on one experience but I'm inclined to say no. After an unsuccessful interview, I was told that my CV would be kept on file should similar positions arise. A few months later, I saw the same job come up again with them but they never contacted me about it. I suppose they could've decided after my interview that I just wasn't suited for the role, instead of it being about the strength of other candidates.
