When you speak with a company or firm
representative in a formal setting,
that person says you have the job, but you have to go through HR first, you tell your colleagues you have the job, you call HR and ask them to expedite the hiring process since you've already been informally offered the job and then wait several weeks to find out you are no longer being
considered for the job, you have fallen victim to a spell of Premature Ejobulation.
