Not sure if you read the footnotes at the bottom but it’s absolutely a credible source. Just because it comes from a website you don’t know, doesn’t make it non-credible. That’s what the footnote is for. Validity.
“Nilson, L. B. (2010). Teaching at Its Best: A Research-Based Resource for College Instructors, 3rd Edition. San Francisco, CA: Jossey-Bass, pp. 36-37”
The info is all sourced directly from a textbook that many masters level (some undergrads too) college students are assigned when they’re majoring in education.
Linda B. Nilson, the author, is the founding director of the Office of Teaching Effectiveness and Innovation at Clemson University. She is the author of The Graphic Syllabus and the Outcomes Map: Communicating Your Course from Jossey-Bass.
Disclaimer: I have hired helped make hire/fire decisions for faculty members but never worked specifically in a College of Nursing.
That aside, she should expect to be asked about her philosophy on teaching and learning. It is possible they may ask her to do a teaching demonstration, but likely they would have conveyed that well in advance.
For new faculty, I used this as my "teaching 101": https://www.amazon.com/Teaching-Its-Best-Research-Based-Instructors/dp/0470401044
Overall, I can't think of anything to avoid. I usually like to be asked 'what is the typical day like,' or something to that effect.
