Walgreens interview questions

Submitted my resume through a recruiter during a job fair at my university. I received a call a few days later to set up a 1:1 interview with a manager. I arrived a few minutes late to the interview because of some unexpected road construction around the store I was interviewing at (I still called to let them know, even though I was only about 5 minutes late). When I arrived, the clerk alerted the manager and he came out to meet me. He took me into the back room and informed me that I had to take a skills assessment first and foremost before he could conduct the interview. He set me up on a computer in the photo lab and I finished the skill assessment 30 minutes later. The manager then led me back into the back room to conduct the interview. I can't remember many of the questions, but many of them were behavioral and situational based. As I answered his questions, I couldn't help but notice that he was pretty apathetic and didn't seem very interested in conducting the interview. Once finished, the manager informed me that, if offered a position, I was not going to be starting out as a management trainee because he found that most of the college graduates were completely unprepared to fulfill the position. Instead, I would have to start from the very bottom as a cashier and work my way up into management. He then gave me his card and said he'd be in touch. After going through the most awkward interview of my life, I was incredibly angry. I felt like they had wasted my time and were completely dishonest with me. It was probably one of the most rude, unprofessional interviews I'd ever experienced. I was happy when I didn't receive a call back.
