Applied Materials interview questions

Applied for the position through linkedin and got a call from the Sr.engineer about 5 months later. I ask him what the position is about and he actually laughed at me for not remembering 10 lines of job description. Nevertheless, I went for an interview next day. It lasted about 30 minutes. 4 guys casually asking general questions, with one guy walking in even more casually in between the interview and asking a technical question, for which I gave the correct answer.He gives me a sarcastic smile and walks out. The questions were mostly "can you do lab work ? "have you handled some particular xx tool earlier " etc which were not even mentioned remotely in the job description. Basically, I think they copy pasted a template of job description for some other job and posted it. The lazy attitude of the people was quite evident in the interview. For technical questions, I answered some questions correctly and did not remember some answers and told them the same since I had very little time to prepare for it. I don't understand the concept of expecting people to know about the exact tools they use and have worked on the exact software they have. I told them I had experience working on similar tools and that i can learn quickly and they had a "whatever" expression. A disaster of an interview.
