Is the person you hired the person you hired?

In a world of remote teams, I have a feeling we're going to be seeing more instances like this in the future.

A reader writes in to Ask A Manager with “the new hire who showed up is not the same person we interviewed.”

"John has different hair and now wears glasses.

John is talking extensively about working in a garage because his three children and wife are home. In the interview, he made references to being single and was visibly in an indoor desk area.

John can’t answer a number of questions that they previously discussed in the interview, things pretty pivotal to the position."
