When you interview for a position, the department and organization you are trying to get hired by also have a story. And they're trying to determine if 'your chapter' fits into 'their book'.
So your goal is to understand, as best you can, what their book is about. You accomplish this by doing your research on the company (the plot), researching the hiring manager, potential co-workers and leadership (the characters) and understanding the industry (the genre).
The more you understand all the components of a potential company's narrative and how your story fits into it, the better your chance of adding your chapter to their tome.
