There are numerous articles on resumes mistakes written by various employers, HR and other resources persons, however there are very obvious mistakes most employers make when posting jobs or in their recruitment process that most of these articles have failed to address. I have tried as much as possible to list some of them below.
Job descriptions are full of typos
Many employers do this (even some jobs posted on Ngcareers) and it is very bad, your job description should be typo free to help potential applicants understand the role required in the position being advertised and the steps you want them to take to apply. Some employer overlook this aspect because of the nature of the industry, they believe no matter the errors in the job details candidates will still apply, at the end they blame candidates for not understanding the job description. In our own effort we try to correct these typos where we can. But this is appalling.
Poor Formatting of job descriptions
Almost every employer/recruiter is guilty of this. Most jobs submitted are poorly formatted, this makes job descriptions hard to read and could make you lose quality applications. We spend several minutes reformatting various jobs published here on Ngcareers.
The length of some job descriptions/ requirements / desired skills is very unbearable.
Most NGO and government agencies are guilty of this, job details are extremely lengthy that you wonder whether this is actually a job description or an employment handbook. While your job description should be detailed, try as much as possible to keep it under reasonable length, to aid the job seeker fully understand your message when applying. Job descriptions between 300 words and 1000 words is ideal, at most keep it under 1500 words (my opinion).
