A good resume is one with a clear message at a glance. One usually doesn't have much time to go through the specifics.

Also, most resumes look more or less the same if you start reading thoroughly. So, what distinguishes you is how much you can convey to a third person in one glance.

However, a crucial point to keep in mind is that the third person may or may not be an IITian. So, your resume needs to be optimally elaborate and detailed.

Be good at a glance and not boring with details.
