Intel Corporation interview questions

I applied through my school's career search. I was first asked to complete a case with a group of 4 other individuals. We were given 30 minutes to complete the case and present our findings. The actual interview was a dual interview. I was interviewed by 30 minutes by two different interviewers.

The longest interview I have attended till date. Most of the questions were from my resume about past projects and a couple of basic question about linked lists (insert, delete). Hypothetical questions like what technology would you use if you have to count the occurrence of all the words from wikipedia within a day. A question on what kind of interaction would you have if you want to recommend products to a user The interview was unusual in the manner it was conducted. The entire time about 3-4 hours was about the resume content.
