Omnicom Group strongly believes in striving for improvement each time we run a client's advertising campaign. In order to do that, the media buying team at Omnicom Group evaluates campaign results and identifies lessons learned from the project.
In your response, identify an important lesson you have learned and how it may have improved future client projects you have worked on. If applicable, include general details about the project to help illustrate. Omnicom Group is looking for media buying team members who are continually looking to improve campaign results for its clients.
