Intel Corporation Integration Engineer interview questions

Scheduled on Monday morning with a bad temper hiring manager. I am an experienced engineer for 8 years, but he keeps interrupted me on my descriptions, and he thinks my work is enough to be considered as a major accomplishment. Really?! Everybody around me gives me a thumb up in my work, and I am impressed by this so-called expert.

Basic semiconductor physics and questions on what the candidate has done in their school works. Total 8 consecutive interviews, and questions on my presentation. All were very kind and helpful
