I am interviewing in a few days for a position requiring some skills I am currently missing. This can be solved by reading one of their manuals, which are supposed to be for sale as far as I understand but the full pdf appears in the very first google page when I search for the document.
I cannot just read it and pretend I got this knowledge from my studies or during previous employment because I cannot prove it and my previous experience has nothing to do with this field. On the other hand, I do not want to lose the opportunity to show motivation and especially learning ability, which is one of my strongest points.
Is there a graceful (and hopefully legal) way to support my action?
