Recruitment consultant: How to write a resume when all my work experiences look the same?

I agree with the answer colleague Omar and added to it. You must remember your business tasks in each job. So there are certainly some of the tasks vary from one function to another. Also, you have worked in several companies so you have to mention them. Because the company name may be added to your job file. Also if the jobs are consecutive "in the sense that you leave a company and work in another." There is no period during which you were unemployed during your previous employment period. This is also a positive point in your job profile. Which means that the mention of all previous jobs in your CV is very important even if it repeated the same job.

Thanks 

Just write your experience by date and add some detials, that was not a problem to have the same work experience
