Lam Research Process Engineer interview questions

The manager of the plasma etching group called me. He asked me to introduce myself, and asked a few questions about my previous experience I listed on the resume. Since I have etching experience, he asked more questions on what I have done with plasma etching, and how did I develop the recipe for the etching, etc. Later, he asked me some behavior questions, like problem-solving. He did pay much attention to this part and expanded the question to details like what if you didn't get expected result in the lab.... Last, he asked me whether I have experience in industry and whether I have taken classes about plasma. The manager interviewed me is very professional.
