Learning Express interview questions

This is a warning to other job applicants. The manager here doesn't know how to conduct interviews. We met and began like any other job interview. I had told her about my current job. They then rejected me on the spot because "I haven't done anything else.", something they have no knowledge about. I even gave a copy of my resume to prove them wrong and show I'm a suitable candidate. I never heard back from them again. This is a massive red flag in my eyes acting like they know your life better than you do when they clearly don't.
