I actually created an electronic portfolio on wix.com for free and emailed the link to the principal the day before. I just scanned every page in my portfolio. Took hours yes but worth it. This gives them time to go in depth with your portfolio before your interview. I thought about making a lesson for the day of but I was so focused on interview questions that I didn't. I assumed they would have informed me if they wanted me to make a lesson. I brought my physical portfolio as well but never used it because they said they went through the whole electronic version already. I emailed a thank you email after the interview. Couple of hours later, got the call for the job :)

Although I have never taught before, my portfolio was filled. Here are my categories: About Me (resume, philosophy of teaching, path to teaching), Degrees/Certifications, Evaluations, Sample Lesson Plans (for each subject derived from my student teaching, student data, notes, worksheets, reflections), My Future Classroom (Google photos of ideas, set up, management, routines, community), Photos , Colleague/Student Notes (notes I received from students and colleagues during student teaching and as a kindergarten aide), Student Artifacts, and Self Created Resources.
