Intel Corporation Intern interview questions

I had one round of telephonic interview. It was mostly based on my resume. Since i had projects related to big data and data mining, most of the questions were related to them. Apart from that he asked me basics of dbms- difference between union and union all; C language- difference between structure and union; oops- difference between abstraction and encapsulation

Referral got me the call. Setup an interview in the next 2 days.
