This is the second truly nontraditional novel I've read for the challenge. Where Important Artifacts. . . by Leanne Shapton was a novel in the form of an auction catalogue, Overqualifed is an epistolary novel with a twist - all the letters are cover letters where the narrator (named, oddly enough, Joey Comeau) seeks employment for a variety of jobs.
This book was a little slow to grow on me. At first, it seemed like little more than a clever stunt - preposterous cover letters written by someone who seems more interested in unloading than impressing. I didn't really see where it was going. Slowly, though, the narrative slipped through and I really started to like it.
The story is actually a lot darker than one would expect - there is far more loss and longing than there are laughs (though there are laughs, as well). And unlike the Shapton book, this is a book I would have liked to see go a little longer.
