Siemens Mobility Software Developer interview questions

I have quite a bit of experience all around. The interviewer was quite rude and said his impression was that I was missing a foundation and it was hard to get. The guy seemed overall annoyed and like he hated his job. Gave me a basic but old styled project. A web app that worked like a photo slider. I also learned AWS and deployed and hosted the web app over the weekend to submit it. No response from the interviewer.
