Intel Corporation Digital Design Engineer interview questions

I was interviewed on phone for like 20 minutes for the position of digital design engineer. I could not perform well since that is not my area of interest.

I applied through career portal, It was 4 hour interview, they have asked easier questions but they cornered on few multi clock designs and ram and rom designs. It was lengthy interview and it was my first so I couldnt answer with confidence, with good preparation and presentation we can do it.
