Old-school Intel uses a lot of "Behavioral Interview" questions, but more and more, this is changing as interviewers are younger employees and those who have come from other companies. You can find sources of sample Behavioral Interview questions on the 'net.
I also urge you to be sure Intel is a place you want to work. It is a fast-paced, highly-political, and unstable employer. It has a history of getting into new businesses but not sticking it out for more than a few months or maybe a couple years. Intel has destroyed virtually every company it has acquired. It lacks upper management leadership to choose a strategic direction and stick with it. In the recent -- and ongoing -- job cuts of over 10K people, it was 100% mid-managers and lower and individual contributors. No upper managers were affected.
