Antony Eagle has written a nice article about interviews. He provides a more detailed survey of the relevant empirical data than I'd seen before (though it is admittedly incomplete), and makes a fairly detailed set of practical suggestions, in light of the fact that it seems to be psychologically impossible not to do at least some kind of interview. (See, for example, Asstro's comment here; I don't mean to distance myself from this attitude. I share it.)
Although this essay is written from the point of view of the interviewer, it seems to me that it's important for job candidates to be up on this stuff. It's a very "noisy" process, and the judgments being made in this deeply imperfect environment are about us. Our asses are on the line. You want to be able to do what you can to diminish the noise, or at least get it to work in your favor, or at least minimize the degree to which it works against you.
Thanks to Dr. Eagle for permission to post.
