I was once asked if I would be OK with writing the Table of Contents even though it had been years since the page was part of my job description. But I said yes, and got the job, and actually didn’t mind doing it until it was eventually taken off my plate a year or so later. Bottom line: Just say yes. Job descriptions are what you make of them once you get your foot in the door—until then, just prove that you’re someone who is willing to roll up your sleeves and get the job done.
