It’s probably best to not hire this candidate. Bribes are not ethical and go against the PMI Code of Ethics. 1 is incorrect because while this may be a joke, it’s likely not an appropriate joke in the situation. 2 is incorrect. The candidate is not yet hired so there’s no firing to do during the interview. 4 is also incorrect. You should not hire the candidate in light of the bribe statement. In addition, the candidate offered you the money, not the company.
