Famous question in the marketing interview, What do you know about marketing?

I hate this question, to me it sounds like "What do you know about life" :)

Marketing is related to sales, In each bog organization should be marketing department 

Marketing is supporting to offer the  tangible or nontangible value so their are many tools assist that by phone calls, media & advertising, social media & broadcasting. Some times no need for marketing because the customer needs let them search for product without any offers 

MARKETING =  DIVIDING+SPREDING
