Studies have shown that attractive people get more attention. Beautiful women, for instance, get promoted more often. But when it comes to APPLYING for the job, sex roles are reversed: Women who attached an attractive photo to their resumes got fewer interviews than men who did the same thing. The researchers think this may be due to the "dumb-blonde hypothesis."
Or it may be because personnel departments are almost always staffed by women. Could they be wary of letting an attractive rival in?
