I have a full-tuition scholarship interview coming up and I have been trying to mentally prepare myself for the entire process. As the suggested attire is business professional, I plan on wearing a business skirt (black?) with a red button down shirt and a black blazer. Is this appropriate attire for the event? Would you suggest anything different? Also, I have been looking on the internet about typical questions in these interviews just so that I could prepare myself for the usual kinds of questions and to stir inside my head some ideas for responses to these questions. What questions do you think are usually asked? What have you all been asked before?
Your attire is fine. The interview is pretty easy for these things. I can’t remember the questions, but I talked extensively about my writing poetry and journalism and the different types of thought involved in those two. From there, it stopped being an interview and became a conversation. Just have a few topics you believe make you an interesting person and are prepared to explain in depth. The only wrong answer is the boring one. Try to speak about your experiences and not just your opinions. I’m rambling but you get the idea.
Also, this is an aside, I don’t know of any full scholarships based on merit. Is that explicitly what you are interviewing for? Or is it something like Questbridge that guarantees 0 efc based on your current income level?
@chowling
University of Southern California provides several full tuition merit scholarships. Just saying.
It is a full tuition scholarship at a university. @chowling
Typical questions would include: why you are interested in that college, your area of academic interest, your ECs, how you spend your free time, community service. My guess is that you filled out a scholarship application - be prepared to elaborate on anything that was asked on there. Often these types of interviews are conducted by panels. If that is the case, always look at whomever is asking the question when it is being asked. Then when responding, start out by looking at the person who asked the question, but make sure you also look at the other panelists/interviewers as you respond. Finish your answer while looking at the person who originally asked the question. Make sure you thank the interviewer(s) for their time and consideration when the interview is over.
Your attire sounds fine. However, just adding - do NOT wear shoes you cannot walk in! No ridiculously high heels. I woud also be minimalist on make-up (if you wear it). Keeps things classic and minimalist but not too boring. 
Good luck!
@chowling Temple has full scholarships based on merit too.
@Leathefuturedoc Your attire sounds good! Most interviewers ask about you and your extracurriculars/hobbies. They want to know about you and what drives you as a person. Depending on your interviewer, the questions may be concrete or abstract. They might range from “What did you enjoy about volunteering?” to “What’s your favorite book and why?” Scholarship interviews might be a little different from alumni interviews. Overall, the concept is the same. They want to know about you. No rehearsal is really necessary–just remember important and interesting details about yourself that you would like them to know and don’t be nervous! Good luck.
