This is intriguing – comment by “B” at http://bit.ly/gYGL6k :
Some of my former co-workers (who were also hiring managers) nixed applicants that responded “Because I love books” to the question “Why do you want to work in a library?” While such a black and white approach to hiring makes me a bit squeamish, I do strongly encourage job applicants to be a bit more creative in their response. Apparently “Because I like books” is such a common response (among the entry-level crowd, at least), that giving a different (thoughtful and honest) answer is a quick way to nail the question in an interview.
