Object Expression interview questions

First I got an email to set the interview date and time. There is no technical test for this position. During the interview session, the interviewer ask me regarding my experience and project that I have been involved. Then he ask a few technical questions and surprisingly I had never meet an interview like this. He laugh at my answer and I wondered if my answer is wrong and he even called me 'useless'. Leaving me with totally shook. How come an interviewer bluntly called the candidate 'useless'? Despite my passion and two years of relevant experience, the interviewer was dismissive and belittled my skills. He also offered a lower salary than my current job. While I understand the importance of feedback, it was delivered in a harsh and discouraging manner. Constructive criticism should motivate and guide candidates, not make them feel inadequate.

Casual interview. Asking a lot of technical stuff but just a basic things based on tech stack you primarily used. Also about personality like how you manage time or stress. Just a common interview question since its for entry level position. Remember to research about company so you can prepare question to ask. As a fresh grad, I'm seeking for professional growth and interviewer cannot provide a clear answer about this, that's why I decline the offer.
