Do people put a computer literacy list on c.v.'s these days or is it a given that everyone will be able to use Office, graphics programs etc?
What about LaTeX - I used that over 12 years ago to write my dissertation, I don't even know if people still use it! I probably could still use it with a manual to hand, but not without. Same for other software I used a long time ago.
The actual software they ask for, I've never used, but have used a different one for a similar job three years ago (stats program)
