Pret A Manger Sales Associate interview questions

This was the fastest interview experience I've ever had because it ended before it even began. A few days after submitting my application online, someone called me to confirm details and set an interview date. On the day of the interview, I eagerly arrived at the store, only for the staff to go and check with the manager. To my surprise, the manager had no idea an interview was scheduled and asked me to wait until they finished their current tasks. After waiting for nearly 20 minutes, I had to leave because I had other appointments in the afternoon. I can't understand why a store would post job vacancies online and schedule interviews if they don’t need staff. To top it all off, they didn't even know someone was supposed to be interviewed. If you fancy a pointless trip and think the 8-pound return fare is easily found on the ground, then by all means, come and experience an interview with this company!
