Choose a field that you are best at and show it to the interviewer. You must be the best in this field. For example, piano, chess, calligraphy, painting, if you like playing the piano, then choose a piano piece that you are best at and difficult, which is your specialty. Without talent, what can we choose? We can opportunistically choose some published papers and articles related to education and our writing level. Or a little magic trick, or recitation and so on.
