Make sure that its current and that the contact information you have for people is up to date. Take all the business cards you get during your job search and enter them into your contact database. Sometimes it helps to add a little note to each entry that is specific to who you met so that when you see that person again, you have an instant connection. Little things like remembering that you interviewed with someone at a company whose children play softball in the summer is a great way to keep the momentum of future conversations going. It also shows potential employers that you are a great listener and truly care about who you’re working with.
