Feldman says, “Individuals who are looking to make a change have to dig their wells before they are thirsty. They have to know these people before they need a job.” Hidden jobs often take a long time to materialize. You essentially have to market yourself to someone who has no vacancies with the knowledge that a vacancy can open in the future. If you wait until you’re unemployed, contacts are harder to come by and you have much more at stake in the process, making new targeted contacts, according to Feldman.
