Guardian Protection Protection Specialist interview questions

I applied online at indeed.com and they called me to ask me some preliminary questions. After that I was scheduled to interview. I was offered the job later in the week but told them I wanted to think about it over the weekend (to make sure it worked out with my spouse.) They emailed me an hour later and redacted their offer, stating they wanted to reorganize their internal employees before hiring someone externally. The manner they handled the situation in was extremely unprofessional.
