FUJIFILM Software Developer interview questions

The process started with a call from the recruiter where he told me a little about the company and the team asked me several questions about my experience and current projects. Then we scheduled a technical interview where we talked about my experience and the things I'm currently working on. Most of the questions were related to JS, but the vacancy clearly says it's for working with backend with Python, C# and C++. I don't know why the interviewer insisted on frontend stuff. From that moment on, I knew I had wasted my time, and I just wanted him to finish asking his questions so I could leave. The workplace looks old, untidy and the elevator stinks of cigarettes, if you are someone who cares about details you will notice that. The only good thing about this interview was the ending.
