As a marketing executive/officer, in your first meeting should you tell the client ideas/suggestions or should you listen to their needs first?

Always listen first.  Show up well prepared, with research done and a few ideas/concepts of course - but the client knows their business far better than you do.  Even more importantly, only the client knows their pain points and can tell you what they want to achieve.  Ideally your research has armed you with enough material to be able to engage with the client in an informed way, ask insightful questions and even anticipate some of their requests.  If you have invested in background research and planning you will be able to field requests with competitive knowledge and set client expectations appropriately. 

Listen to the client's need and understand their pain areas, analyse what and where can one improvise on current marketing campaign
