How do I properly prepare for a graduate school interview?
In addition to thinking about your answers for the most commonly asked grad school interview questions, you should reach out to former and current students to ask their advice on preparing and what sort of questions will be asked.
Look back through your resume and come up with anecdotes that you could use for common questions, particularly those that ask about obstacles that you overcame. If you’re applying for a research program, ensure that you can talk about the previous research experience you’ve had.
You should also read as much research in your field as possible. Research the faculty at the schools you’re applying to and read some of their papers. Come up with a few questions that you could ask them.
