Air Hygiene interview questions

It was an easygoing conversion about the role and my preferences and interest, with the opportunity to ask lots of questions. But then the interviewer never called for the second interview that was scheduled, just nothing. I thought it was rather unprofessional, especially after reading how the company's owners cared, etc.

The interview was an in person interview at the school career fair. The interviewer was kind and the interview was simple, they just want honest answers as there is a lot of travel and the travel and manual labor is not for everyone.
