Do a Google search and read through their website. I just did it and you can too.

Read the job advertisement you are responding to to learn what skills and experience they are looking for. Be prepared to talk about how your skills and experience would be a good fit for the company.

Search trade publications/websites for information about the company that you can mention during the interview.
