I would like to know how to write a resume since I have no job experience.
Let’s look at what you *have* done. If you have done an internship, that should be listed. If you’ve been an active member of some club or organization (in school or otherwise), the type of member work you did should be listed. If you have been part of some nonprofit, volunteer organization, that should be listed.
Put these in chronological order.
You’ll want to describe what you did under the name of the organization. Do not make the description a shopping list of job functions and duties. Show things you did that had an impact on what was happening. If you led the group in doing something, discuss how many were part of the group and what the group accomplished. If you came up with a novel idea of getting something done or saved the day in some regard, list that and how much was saved — or earned.
What skills you have should also be listed under another section. If you are looking for photography work, the types of cameras you know how to use, whether you can develop film, lenses you use, special techniques should be listed. This is similar to listing a typing speed if it is of interest to those who would be evaluating your resume, as well as any IT skills (HTML coding, graphic work, knowledge of Excel or PowerPoint).
