Intel Corporation interview questions

HR sent me a phone interview invition. After I replied to the email, the interview date was set to be the day after. During the phone interview screen, They have a list of questions based on basic circuit design skills. Those questions are not hard. There are also questions about the knowledge of the trend for computer development. At last, they asked some questions about the transmission line technology which I am not very familiar with. The interview last about 30 mins. I got a rejection letter half hours after the interview. I thought my background may not match their requirment.

Initial engagement during campus recruiting event, followed by one interview by two senior verification engineers. The process usually involves another interview by a manager.
