Publix interview questions

Before being called in for an interview, there was a required long online survey. A week or two after completing the survey, I was called into the store location office, and asked about my previous experience (I was a high school junior) with normal behavioral questions. Afterwards, the manager asked me if I'd be available to start working next week. I calmly stated that on my application I put that I would be ready to work during the summer (in a month or two). The manager apologized for wasting my time, and said they only were looking for applicants now, and not during the summer.
