ScienceLogic Software Developer interview questions

Initial video screen call. They were impressed with my experience so they fast tracked me into the next video call with a manager. Same again. Very impressed, Very lovely people to talk with. I was then fast tracked to video call their Software Architect. He was very cold from the start, and I felt he took issue with my previous job title that was higher than his own. I was asked to explain my experience, and then was asked some unexpected questions. The types of questions that you Google when you need them, and don't commit to memory. I was then rejected with a generic, "not experienced" enough email. - Funny because the job description said they wanted someone that had room to grow and learn! (not a senior position) - I asked for further clarification on which part I failed on, but received no response.
