There are many reasons not to hire someone, but if the candidate admits to lying and stealing in the interview, they shouldn’t be surprised not to get the job.
When digging in to the technical skills of a recent candidate, they were proud to tell me about their awesome home setup for which they stole a high-speed internet connection. When talking about teamwork, he told me how he refused to tell teammates how he did things, lied about what he did, and that he enjoyed hacking into his coworkers’ machines.
Double fail. Both that he was stealing services, lying to his coworkers and generally being difficult to work with, and because he was dumb enough to let that be known in an interview.
