I had a 30-minute interview for a MERN Stack Developer position. The interviewer arrived 10 minutes late, which was okay, but he started asking questions unrelated to my domain. I tried to answer them, but then I realized he was referring to the wrong resume. When he mentioned something that wasn’t in my resume, I corrected him. After that, he asked only one question — and that too was about Angular, even though my experience is in React — and then ended the interview.
