Applied Materials interview questions

Very long and frustratrating. Online interview Then home assignment Then office technical interview Director interview. They kept me hanging by a thread.. They told me that they try to solve I too, which makes me think I did the job for them for free. They scheduled all interviews to one hour. At reality it lasted three hours each! The director failed me and I have no idea why. It lasted 30 min in zoom and he actually read the questions from a form and just wrote my answers. barley had any discussion with the rude dude.

Four 1 on 1 meetings with four people, they work in the same group. I introduced myself and research experience, followed by some related questions and behaviors questions. Everyone asked that why do you choose this company.
