I’m applying for analyst internships. 1) Would they prefer CV’s or resumes? 2) If resumes, how many pages (one page max?)? THX

  1. Cover letters with resumes. 2. One page max.

Whats the difference between a CV & resume? I thought they were the same. Here is US, acceptable format is a Cover letter (tailored towards the company and the job) + a resume. 1 page if you are a fresh grad, if more than 7-8 year experience and education (masters etc), 2 pages would be fine as well.
