How did you come to know about this position?

When they ask, "how did you come to know about this position?" the interviewer needs to know whether you've taken the time to look into the organization and if have an honest purpose behind wanting to talk with them. Say an item, a purpose statement on the site, a reputation for capable representatives, or whatever else appears to be relevant to that particular organization. Think of an incredible reason. Try not to influence it to seem as though they're only one organization among many.
