Fisdom Front End Developer interview questions

I was contacted by the HR department and an interview was scheduled for me. During the interview, I encountered a situation where the interviewer exhibited unprofessional and discourteous behavior. When I expressed uncertainty regarding certain questions, the interviewer responded with disparaging comments about my career and experience, remarking on the number of years I've been in the field and expressing incredulity that I was not familiar with certain aspects of my work. Additionally, the interviewer exhibited inappropriate laughter throughout the interaction. Which should not be entertained.
