ASML Engineer interview questions

I applied online and a recruiter contacted me after two weeks to arrange first phone interview. The interview lasted around 30 minutes. She asked me about my educational background, programming skills and why I wanted to join ASML. After another two weeks, another recruiter contacted me to arrange second phone interview with a professional person. I was expecting a more professional talk around the posted vacancy and and my research experiences . However, the guy ended up asking me high school physics and math formulas rather than conceptual questions. He never looked my CV even. I have never experienced such kind of interview at a professional level. I am sure high school student will remember all the formulas better than one who finished high school 10 or more years ago.
