How Far Should a Job Screening Go?

SlashSquatch asks: "My sister is getting screened for a programming position with a financial firm. I was alarmed to hear she'll be getting fingerprinted at the Sheriff's Office as part of the screening process. Instantly I conjure up scenes of frame-ups and corporate scandals. I want to know, should this raise a flag? Would you submit to fingerprinting, blood tests and who knows what else (financial, genetic code, and so forth) for a programming position?"
