You should be able to find out a lot of information about the company’s history, mission, values, staff, culture, and recent successes on its website. If the company has a blog and a social media presence, they can be useful places to look, too.
You can do this by tying what you’ve learned about the company into your responses. For example, you might say: "I noticed that when you implemented a new software system last year, your customer satisfaction ratings improved dramatically. I am well-versed in the latest technologies from my experience with developing software at ABC, and appreciate a company who strives to be a leader in its industry."
