Keeping your resume lengthy or short, which one among the two is better generally depends on what kind of information you have put into your resume. Now, If you are making a three-page resume, you should make sure that your resume is interesting from the starting till the end, because if the recruiter finds it uninteresting he would not waste his time. Now, for the freshers, like college-going students, 1-1.5 pages of the resume is enough because they do not have any work experience to elaborate. Once, you are experienced, you can write more in your resume.
