Auditing is time consuming. Had two different long term temp jobs in my early 20s in the 1990s that were involved in aspects of auditing. Typed 110 wpm with 99% accuracy so I was good at data entry and auditing needs a lot of accurate data entry and careful cross-referencing.
But the most fun audit I was involved in involved sales force at a pharamceutical company. I didn’t know what they needed my work for at the time and I signed three layers of non disclosure agreements. But I had to create a system in Microsoft Excel that could process a shit ton of data that were being scanned in by a team in the room next to me, doublechecking their scans and then processing the results, to look for anomolies.
Mind you, I wasn’t trained for this. I was a systems analyst by a quirk, not a degree, not a data analyst really either, but I knew how to whip together analysis and find out what’s misfits.
Later on I found out it was for sales force that were stealing drugs and reselling them out of their garages and all the handful zip codes I highlighed out of thousands and thousands represented exactly who was stealing.
47 sales reps got not only fired but jailed for the amount of theft they were doing. And it wasn’t even INTERESTING drugs they were peddling.
