The sanitization process should also be repeated in the interview process. Only objective information is taken down by the interviewer, and this is passed on to someone else, who can make a value judgement about the candidate without that judgement being coloured by the candidates gender, race, looks, height, perfume or whatever else is considered to be extraneous information.
Are you being sarcastic? This would be expensive, and is that how you are going to work with them?
I know that HN and the world in general is on a kick about equality of everything, but when your interviewee wears 100 gallons of perfume to the interview that is a problem I have to address even before they start working.
I absolutely think that the work can have objective measures, but back in reality much of work is not based around how good the candidate fits the job description exactly as described in the requirements.
That's not really fair to the candidate when you remember the potential employee is also interviewing the employer. I don't think I'd want to work somewhere that thought myself and my boss' should not meet.
