Function

• Avoid listing "Customer Service Representative" as a previous job (even if that was your official title.) You want to stand out among all the other ex-Customer Service Representatives who may be sending in resumes for the same position, so try something like "Customer Care Specialist" instead. It doesn't matter if this isn't exactly what your ex-employer's HR department had you listed as in the official books. The job descriptions are identical, so you're not falsifying your resume, and use of the word "specialist" subconsciously implies that you are a "go-to" person with a specialized skill set.
  
  

Features

• Append the name of the department or the type of work you did to the job title. For example, "Customer Care Specialist - Payments Recievable" or "Support Services Agent - Travel Insurance" look more interesting than "Customer Service Representative" even though it refers to the same job. Tacking on the specific field in which you worked your customer service job tells employers that you have specialized knowledge and skills beyond the average call center worker.
  
  

Duties

• No matter how creative of a Job Title you come up with, the bullet points under the header will make or break the job description. Be specific. Instead of "Answered phones", say, "Provided outstanding phone support for account holders with questions about their cable television, telephone and high-speed internet services." Instead of "used computers", mention the specific software and procedures you were trained in.
  
  

Achievements

• Don't limit your bullet points to the activities you did every day. Include specific events that speak to your abilities and ambitions. Were you ever employee of the month? Add it. Were you in the top 5% of your department for overall call resolution? Add it. Did you get 100% ratings on call quality audits? Add it. The job itself can be mundane, but that doesn't mean that you are. Use your resume to show that you can do exceptional things in ordinary circumstances.
  
  

Cover Letter

• Sometimes the hardest thing to do in a resume is link a customer service job to the new job you're applying to in a meaningful way. A well-written cover letter affords you an opportunity to make up for this. For example, say you just left an IT Call Center/Helpdesk position and are applying to be a Network Administrator. You might say, "The daily combination of customer-facing support and hands-on technical work at my last job makes me well-suited for a role as a Network Administrator, because not only can I fix network problems, I can also effectively communicate information about outages and upgrades to end users." This information may not fit well into the body of the resume, but including it in the cover letter shows that you not only have an understanding of the job you are applying for, but that you are enthusiastic about utilizing and building upon your customer service skill set in the new role.
