Prior to interviewing, it is imperative that you conduct enough research on the interviewing organization that you can talk about their internal structure, any awards or recognition they have received, and how you feel you will fit with their company culture. Research multiple sources (website, google, glassdoor.com) as well.
"I was familiar with your firm prior to my interview but have conducted more in-depth research since being invited for an interview. I understand your structure quite well and really appreciate the time and funds your organization puts back into the community through your variety of charities. Your employees seem to have great things to say, and I was happy to see that you ranked as one of the top rated employers in the financial sector. All very impressive!"
