Know Your Stuff - You should be prepared to discuss specific aspects of the school that interest you, programs you may be interested in, and any other particulars of the college that are uniquely well-suited to you.
Prepare Your Own Questions - Keep in mind that these questions should show that you have done your due diligence already, so avoid questions whose answers are readily available on the Internet or elsewhere.
Anticipate Common Interview Questions - While most interviews will consist of some unique questions that you can’t anticipate in advance, many will also have at least one or two common interview questions that are easy to prepare for when you consider them in advance.
Practice - No matter how much time you spend researching a college and anticipating possible interview questions, there is no substitute for actual practice.
Be Early - The common expression here holds true—if you’re not early, you’re late. In order to put your best foot forward, it’s a good idea to arrive for your interview with time to spare.
Be Your (Best) Self - Your interviewer wants to get to know you as an individual, so it’s important that you’re able to relax enough that your personality and voice can shine through.
Dress Up, But Comfortably - If no specific information is given about attire for the interview, you can assume that you should dress in polished clothing, but clothing is comfortable.
Don’t Look At Your Watch - Looking at your watch, the clock, or simply gazing off into the distance can make it seem like you’re in a hurry to get the process over or you aren’t focused on the task at hand.
