Tips on answering "What can you do to enhance our department?" and "Why are you a good fit?" type of questions in job interview I am preparing myself for a job interview for a lecturer position.  According to many articles on academic job interviews, a common question to be prepared for is that " what can you do to enhance our department?"
I'm  not sure what exactly the committee would mean by that? I understand that I should tailor my own answer but question is not really clear to me.
This is an update for those who are planning to go down this route:
I had my interview. I was asked a lot of questions regarding my teaching philosophy and experience. 


I was asked why I like to teach at their university?(to protect my privacy name of university will remain anonymous-but lets say it's a prestigous research university). 
One particular question I was asked was that what was the most difficult part of teaching I ever faced and how I dealt with that. 
Also they named a few courses and asked if I've taught them before. 
They asked if I have ever taught classes as instructor and not a TA. 
They asked a follow up question asking if I did  A to Z of the course preparation myself, e.g. writing syllabus, making exams etc. 


At any rate, while I didn't get the cliche of why-are-you-a-good-fit? the committee aimed to get to know me and investigate my teaching skills in detail by asking straightforward  questions.
