I moved to a new position recently and was involved with hiring my replacement. We got a good hire, but one of the people my bosses initially wanted to shortlist had an impressive resume, but then you go on LinkedIn and there are two profiles. Same exact headshot. Similar names, as if one of them could be a nickname and one a full name. Career timelines are totally different though.

So just by doing a little pre-interview prep, I found out that this person (if it was a real person and not a persona of some kind) had a resume with one career timeline and two LI profiles with two separate and different career timelines.

Fed this to my bosses who proceeded to have an extremely awkward and brief interview with the person (or the person posing as the person) about "so, in 2022, were you at $FIRST_COMPANY, $SECOND_COMPANY, or $THIRD_COMPANY?" I mean, you have to pass a background check to work at my company even if offered; why do people do this?
