Fragen im Vorstellungsgespräch für Beschäftigung als Senior Web Developer Team Lead bei Netquall Technologies

I am a senior resource with 5 years of work experience, but the interviewer at NetQuall does not have professional sense to talk to a senior resource. I have called through a recruitment agency for interview. I have cleared the first round of interview with excellent score. Then they told that I have to appear for HR round in the evening. But instead of HR round it was technical round while I appeared there in the evening. In this second round they sent interviewer, who was mentally upset. He asked me 2 queries about codeIgniter. While I was trying to respond to him, he was not letting me speak but repeating his question again and again like cracked mentally upset personality. Then I asked him, "Sir, would you like to interview me or I should go", He told me to leave. What is this, the professionalism of a US based company.
