That happened to me once - went for an interview at a school for something reception/pa related. We all (about 6 of us) arrived at same time, were given a short tour, then told he would interview us all separately and to sort out the order ourselves?!!
Two people immediately shouted first and second, others quickly made their place known. The first interviewee was in for 30 mins, when they came out number 2 stood up, as did I, and I announced to the Head that I had work to get back to and left!!
I left feeling very proud of myself, knowing there’s no way I would work for a place that had so little respect of our time!
Another interview I had at a doctors surgery, had a successful (I thought) interview but they asked me to go into their sister surgery later in the week, asking me to meet their practice manager for an hour as half the job was based there. I arrived at 9am, as asked, manager had no idea I was coming so she sat me at reception, shadowing a receptionist. At 10am I asked practice manager if she had time for our meeting, she said no just stay there. 1030 somebody made tea/coffee for all the staff but ignored me!
stayed til 1130, spoke to practice manager again who said she didn’t even know why I was there!! I then walked out , saying i didn’t either!
Got a phone call later that day from original interviewer offering me the job! I politely refused saying I enjoy a challenge but I’d never work for anywhere that disorganised.
