Getting a leg up
There are many different ways that employees come to work for the CDC. If you are currently a high school or college student, you might be able to get a jump on the competition by working as an intern through the CDC's Pathways Program. In addition, if you are a recent college graduate, the Pathways Program could offer you a chance to gain work experience in the public health field or other related support occupation. Students in the program do receive a salary, but are not entitled to federal benefits.
The application process
If you do not qualify for the Pathways Program, there are two ways to seek employment by accessing the current job openings for the CDC. The first is by going to the Employment Home page on the agency's website and clicking on the appropriate link that best describes your situation (i.e. General Public, Current or Former Federal Employees, etc.). The second way is to bypass the CDC page and go directly to where the links on that page will carry you anyway, which is to the government website USA Jobs. Either way, once you are there, you will fill in CDC for the keyword and Atlanta for the location that you are interested in.
Before you apply for a job, however, it is important to note that some positions are initially offered first to current CDC employees or to those who have previously or are currently working as a federal employee. You can determine whether you are eligible for the position by looking at the field "Who May Apply" on each job position. Once you have determined you are eligible, click on the job title and you'll be routed to an online application.
The interview process
The interview process for CDC job candidates varies depending on the position that is applied for and the department it is in. Some interviews are initially conducted by telephone, and candidates who successfully pass the initial phone interview are then invited for either a one-on-one interview with a selecting official or by a group panel of three to five individuals who are knowledgeable about the job.
Job candidates who have successfully navigated through the interview process can expect to receive a "tentative" offer of employment. This offer is then followed by a formal letter that provides the terms and conditions of employment. New hires typically can expect to start their position in two to four weeks.
