SupplyHouse.com Web Developer Intern interview questions

I had 3 rounds of interview starting with one HR call which was really nice following with 3 interviews back to back starting with behavioral round with HR, simple questions about yourself. Next, interview with the tech lead, the lead was super humble and also really impressed with my skills but the next round was with the Manager who just barged in the second round and started asking me questions about C++ and Java but in the job description it was mentioned PHP, SQL, HTML. I was caught off guard. He insulted me and said probably wait for rejection thats it and left.
