Lam Research interview questions

Went to an initial screening about a month ago, and then went to a second round over a week later. But it's been 2 weeks now and I was ghosted. This is disrespectful of the interviewer's time.

I had an one-hour phone interview with the person who recommended me. Then, after about a month, they wanted me to fly in for an on-site interview. I gave a 30-min presentation about my PhD work and the interviewers would frequently break in to ask sharp questions on the fly. Then, six separate one-on-one interviews followed, and all the six interviewers well PhD process engineers. They asked a variety of technical, behavioral, and casual questions. Regarding technical, they asked questions related to vacuum science, thin film deposition techniques (PVD, CVD, and ALD), semiconductor physics, etc. They wanted to see if I had strong fundamentals and evaluate my critical thinking and problem solving skills.
