I have worked at Intel over 10 years, and been on the interview selection for several candidates. If you were recommended by a current employee (rather than through a recruiting office), you will be fast tracked on part of the interview process. While the interviews may look mostly like cookie cutter technical interviews there is a lot of behavioral interviewing behind the scenes. Almost as important as technical competence is whether or not the candidate looks to be a good fit for the team they will be going in to. Interviews are often targeted to get you out of your comfort zone and make you feel like you are going to sink. This is the most important time to be confident but not try to bull your way through. If you have limited knowledge in an area say so, and also confirm you know how to get the competence you will need. As a simple example: what is Ohm's law? If you didn't know this (and you should for a technical position) then the "right answer" would be to note that you don't have it memorized but it's in your "art of Electronics" text and you would look it up if you needed it. Intel is big on confidence without cockiness. Making yourself out to be a team player is good. Two of the big catchphrases we use internally is: Be open and direct, and disagree and commit. The first basically means don't back stab, the second means if you disagree with the current plan but are out voted or out ranked, that's fine. Commit to make the plan that is in order work to the best of your ability.
