Before the interview, do some research on the company. You want to be prepared to ask intelligent questions about the position, and knowing something about the company, its history and its culture, is the best way to prepare your questions.
Go to the company’s website. Review the information there, including biographical information about the board and administration. Is there an organizational chart? Make notes about the information you find—and don’t find.
Do you know anyone who works at the organization? They don’t need to work in the area you’re interviewing for. Talk to them about the culture. What’s it like to work at that company?
If you don’t know anyone, go to LinkedIn and look for employees. If you find a mutual connection, ask for an introduction.
While you’re at it, be sure you know where the company is. Print a map, or put the address in your Smartphone. Showing up late does not make for a good impression.
Do you know who you will be meeting with? You may want to look them up on LinkedIn; they have probably already checked the social networks for you.
