Integro Technologies Pte Software Engineer(Internship) interview questions

Very negative experience. The interviewer was not paying attention when I am speaking. Was being cut off multiple times. Personal experiences are being laughed at. Being laugh at things which I am not known of. He could've just told me instead of laughing at me. Feel like being looked down upon. Worst of all -> "What you learn is useless" wtf, that's how you interview?
