Don't do exit interviews. Do "entry interviews". Let the managers sit down with the new hire and ask, "What are your favorite projects?" "What goals do you wish to pursue."Don't forget to ask them, "What is broken in our interview process and how do we fix it?"Crowdsource your requests to ask for help with an unproven idea. Get a group of experts to weigh in. Build a bridge with what is familiar within the organization and people who are outside of your organization.
