The qualifications are mostly physical: a physically disabled person* would necessarily struggle or be unable to do the physical auditing out in the field.

The regions involved vary wildly, depending on where infrastructure needs auditing (either because of catching up on the utility's own documentation, or updating a competitor's docs that they're buying out). Medium to large cities of differing climates.

People in this role either choose to remain in a region for around a year, or move to various areas as a perk/"vacation".

I was introduced to it by what I found out to be a really disorganized and mildly unethical group, which is why I'm not currently out doing it!; looking to forge a new group with trustworthy people, who also know what a damn computer is!

*(but, if you're reading this and strongly interested/motivated, you may be able to assist on the documentation side or more!)
