DO YOUR RESEARCH.
The most important thing for you to do is research the school and program you are applying to before the interview. (You should've already done this, but now in FULL detail). Come in already knowing about the program, certain professors (by name), and current grants/studies so you look prepared. Go to the program's website, check out their FAQs, and read around a little.
ASK QUESTIONS.
Yes they are interviewing you, but this is also your chance to interview THEM to be sure they are a good match for your lifestyle. Come into the interview with a written list of questions. Bring out the actual list and read off it when you ask the questions. HINT: DON'T ask about money right off the bat. HINT HINT: DON'T ask a question that is blatantly stated on the website. Here you want to ask questions such as: how long should the entire program take, is part time study ever an option, what type of jobs do alumni get, are there any grants/scholarships available that can help me with payments, etc.
BRING YOUR MATERIALS.
Look like you know what you're doing. Bring a pen and a piece of paper to take notes on. Bring two pens, just because you're on top of it like that. Wear something presentable. Bring a couple copies of your résumé or CV so when/if someone asks for it you are prepared. (Oh this old thing?? Here ya go!)
TALK YOURSELF UP, GIRL! (Or guy. Whatevs)
Remember that time you did volunteer work that you hated while it was happening but now totally relates to your field? Talk it up. That awesome paper you wrote in undergrad that you're passionate about and got a good grade on? Talk it up. The skills you got from working in a fast paced restaurant environment where you had to be friendly, organized, and calm at all times?? Bring all that up. And put a positive, educational spin on it. Write down KEYWORDS that describe you and your work ethic so you can glance down and bring them up during conversation (examples: motivated, dedicated, studious, organized, punctual, hard worker, etc.)
THINGS THAT ARE IMPORTANT (but don't sweat it all)
When applying to schools, all of these are important but don't put TOO much emphasis on each one. You will be way better in one category and lack another, but that's okay. Rock what you got.
-GPA (overall and subject)
-SAT or GRE scores
-Letters of recommendation (Start planting the seeds for this early on. If there's a teacher that you really liked, keep in touch. Email them randomly to say hello and tell them what you're--educationally--up to. But don't be creepy about it. Teachers will be more likely to actually remember you and more willing to write a letter of reccomendation.)
-Volunteer experience
-Work experience
-Research experience (this is becoming more and more in demand nowadays)
-Entrance essay
-Writing samples
The most important thing for an interview is to go in confidently. Look presentable, be prepared, have a pen, and smile at everyone in the building (you never know who they are or who they know). Yes you are mainly in the hot seat, but you want to make sure this place is a fit for you as well.
