A common interview question is a variation of<p>"Tell me about a situation where you had to solve a difficult problem."<p>Do you all keep track of the difficult problems/projects you've worked on at work? How? Do you write them down? Do you just remember them when necessary?
"Difficult problems" tend to be the ones that you need a few stiff drinks to forget whenever they come up. There should be no difficulty remembering them.<p>That being said, what I'd do if I were in your shoes is create 2 copies of your resume: a copy for handing out and another copy annotated with notes for each job you list about what you'd want to highlight during an interview. Every time your current employer has a performance review, update both since that's when you'll be focused on your important accomplishments over the past review period.
