I have changed jobs often. At one moment, I turned to informational interviews to ensure I was a good fit with the company. I started engaging in a structured dialogue with employees of the organizations I enjoyed. The beauty of such an approach is that you collect intel without any pressure (caused by a sudden job loss, leaving you to scramble for a new role). Informational interviews unlock insight for you. A fan of the cross-functional approach, I recommend using informational interviews at the beginning of a change project. Ask employees about their vision for the future organization, which roadblocks they identify, and what they would optimize if they were the CEO.
