Yahoo Android Engineer interview questions

Applied online, then recruiter sent me an email with employment questions and scheduled a technical phone interview. Interviewer was really rude and talked down to me throughout the process. He asked me if I had experience with some IOS products even though my experience was in android and when I said no. The response was like "What??? You never even worked with that???" For the technical interview he continued to insult me. When I asked if I could quickly look up how to do an exponent operation he was like "WOW. You know a number squared is just the number multiplied by itself right? It's basic fifth grade math!!" And he repeated "it's fifth grade math" several times. How cringe. And to top it off after I solved the problem he gave me the wrong feedback. I used recursion and he said I should have used a whole loop. They are literally the same thing. I knew I wasn't going to move forward even at the beginning of the interview by the way this guy was already talking down to me. But wow - yahoo doesn't exactly have a great reputation for being tech progressive but I didn't realize their interviewers had such a chip on their shoulder.
