What drives your vision when planning a wedding?
Wedding planners are hired for a number of reasons, one of which is to offer vision and ideas. You will be expected to understand and listen to the engaged couple, their interests, and their needs, and use that information to drive your vision. The interviewer is ensuring that you strike a balance and to what degree.
"The couple. Always the couple. My job is to support their vision with ideas and industry expertise, and all of what I do will always be guided by their vision. Sometimes, I have couples that don't entirely know what their vision is, so I will work with them to understand the core of who they are as a couple and propose a plan to them based on my knowledge of their relationship and the industry. No matter what, I always use the couple as my guide."
