I have handled hundreds of background (antecedent verification) checks across a cross-section of various levels in sales, marketing, finance, HR, and IT. It is our company policy that house visits and neighborhood verification are part of our investigation. The inquiries with the past employers are not only through phone or email. We undertake travel of more than 600 km to ascertain the whole background of employment and the standard of living of the candidates.
I have met several candidates of different economic backgrounds. It is done well within the knowledge of both parties and is carried out in such a way that the right candidates do not get upset, and the wrong candidates are filtered out or services dispensed with. Great care, patience, knack, and a host of other skills are required to cull out valid and valuable information. There should be no emotional or personal attachment to any candidate's profile.
Finally, the findings and analysis of the observation of any candidate should be maturely handled. There should be no personal bias on any parameters of a profile.
In my experience, I have come across legal cases, credit card fraud, misappropriation of cash to the tune of crores, indiscipline, blue-collar offenses, connivance, misleading information, data theft, disproportionate standard of living, which are all startling findings in our investigation. It is not detective work, but it all involves a lot of human resources and an analysis of the sea of input that you gather in your process.
Finally, there should be absolute 100% integrity in your reports. The scope of imagination or assumption does not find a place because it is a service concerned with the larger interests of all, and in particular the employers where the stake is in multiple dimensions and large.
