TPIsoftware Front End Developer interview questions

Basic logic tests and basic concepts of javascript, and talked with HR to understand my experiences as a front-end engineer, but my front-end-related work experience is less than one year. They sent an interview invitation to me, emphasizing the experience of front-end, the "years". Their tech supervisor was late for my interview, and the HR and I waited for 30 minutes. And he really disrespect me and just had 5-minutes-talk to me. The interview is an online interview, and he was outside the screen and I could not see him.
