Cumberland County Public Schools interview questions

I sent an email to HR, a principal, and a few teachers regarding an opportunity to provide educational resources to students, faculty and staff. I was then called for an interview for a CTE Teaching position. The interview began about 15 after my arrival. It was a panel interview and they asked the standard questions while taking notes. After about 10-15 minutes or so, one interview checked her cell phone and prompted to leave the room with a 2nd interviewer. Then a 3rd prompted to leave, but sat back down to abruptly conclude the interview. I was not made aware of any emergency or other reason as to why they walked out, but I've never had this happen during an interview. So I assumed it was an emergency and gave out my resume to which, to my surprise, they did not have and had not seen.

It was a brief interview, and I received a job offer on the spot. It took me by surprise because I was only asked a few questions in regards to my qualifications and experiences. It was a pretty informal interview and it was very different from other interviews that I have done.
