What do you do when you purchase too many job slots on a job board? You use them and fill with the duplicates of the jobs you need to fill or write a generic job spec for the type of the jobs you are hiring for, and publish those.
Duplicates, Duplicates, Duplicates…
The advantage in having the same job published exactly the same more than once on a job board is very low. In taking some time and changing each copy so that it has a unique title, and quite different job description will generate more applications, but will also result in a lot of duplicate applications. (you asked for it!)
If you are recruiting for a position where you require a large number of the staff with the similar skills, and they tend not to stay that long with you (students, etc), than you need to have the same job advertised al all times on the job boards.
Just a note on the job title advertised as ‘Speculative Positions’: Putting the ‘Speculative Positions’ as a title of a job advertised on a jobs board will not really do you any good. An DBA Guru is far more likely to click on a job that includes a word DBA than on a job titled ‘Speculative Positions’.
If you want to get a large number of the CV’s for the job published, just write a loose Requirements. Many job seekers use the Job Requirements to ‘filter themselves out’. If you write 6 separate requirements, and one is ‘6 years industry experience’, you might lose someone how has all the other five but only 5 years experience. And that is certainly no recruiters intention.
If you remove the requirements completely, you just mark them as the ‘Desired Candidate Requirements’, or just note that the candidate should have at least 2 of 6 listed, you will increase the number of the applications, while not drastically decreasing the overall quality of the job applications.
