It's beneficial for job seekers to understand the ins and outs of the recruitment process when they're actively looking for work. Applicants who use job boards and online job sites are likely to read many job descriptions and specifications during their search.

So, what is the difference between job descriptions and specifications, and which is most important? Job descriptions and job specifications are two similar tools, which are often used interchangeably, but there is a subtle difference between them. We explore everything a job seeker needs to know to be properly informed when applying for a new job.

Job description

The job description is a brief statement that tells the general information about the job. In plain English, it is where the nature of the job is described. The job description is briefly taken from the job analysis, and it comprises of information about the workplace, duty-timing, salary, responsibilities, and other general information.

Job specification

The job specification derives from the job description; it is one of the most important readable information for the job-hunter as it tells about the eligibility criteria for the certain post. The job specification holds information regarding the eligibilities for the vacancy. It lets applicants know what skills, level of experience, education, and abilities are required for the role. As mentioned in our Candidate series, a good CV (curriculum vitae) is one that is tailored to a job’s specifications. Using a job’s specification in an application is like answering a recruiter’s questions before they have even asked them and sets those apart from others.
