There are so many things at play here: 1) They're in school and are immersed in a certain kind of idealism that doesn't seem idealistic. They're learning techniques and maybe going over research data. Of course, after 4 years, they're immersed in the "language." All of this isn't necessarily bad--it's just different from reality. 2) They're young and enthusiastic and they're going to give a good interview, of course. And, of course, the profs had some hand in selecting the young lady interviewed.
Note: I'm a teacher. I work with new teachers, and I just finished a master's degree in a related field.
