I wonder how this squares with job application disclaimers that try to convince you that: a) You must not apply unless you meet all of the minimum prerequisites as stated on the listing b) Lying in any way on the form is tantamount to committing a felony If IBM realizes their mistake and corrects the listing, are they obligated to immediately reject all of the previous applicants who knowingly submitted false information on their application because the claim was, by definition, impossible?
