When employers interview candidates, they can be as nervous as you are. Sometimes they have experience interviewing, and other times they don’t. They will want you to do well in your interview, so they may start the interview with some chatter to help you relax. In return, you can also help them relax simply by smiling, appearing ready, and encouraging their questions.
You do not need to memorize answers to questions. If you do, what you say can seem forced, as though you are acting a part in a play. However, it is important for you to think about strong examples of your skills and background that you want to share. You can use your portfolio to support the answers that you provide and to highlight actual examples of your work. It is also helpful as a demonstration of how organized and thorough you are.
