I have an awful lot of different versions of my CV, on my laptop. It's probably because I never settle on one particular type of job, when I'm job-hunting. But I have a different-looking CV for every job I've applied for in the last six years, each one trying to highlight a slightly different array of skills and experience.
Job-hunting would be so much simpler if I could just sent my entire working-life story to each and every potential employer. But then, job-hunting would probably be a lot less successful.
So I've just put the finishing touches on my latest CV, which I plan to send to any junior tech-writing vacancies that come to my attention. But if I see a library-type position advertised then I'll have to go find one of my older CVs and create CV-version-twenty-something. I suppose all this re-writing of CVs must be good writing practice. Or something. But I also makes me nostalgic for the days when I was in the same job for years, and expected to still be there now.
