Recruiters use job postings to find the right fit for a position. The entire process is to build the reputation of the company as a worthy employer to work with. The posting should look professional in every sense of the word.
Job Seekers' Complaint
Candidates expect job postings to be drafted by recruiters and not by those who don't know much about the job position. If the job description is not properly drafted, candidates don't understand what they are expected to do. They don't like the posting to beat around the bush and talk about different attributes, capabilities, and specialties, creating confusion. Job posting content should be specific so that there is no confusion. Only then can you expect your opening to be easily filled.
Hiring managers should have a thorough knowledge of the trends in the industry. They should also be well aware of the type of candidates their company would like to hire.
Being distant from industry trends and requirements implies that the hiring coordinator does not understand the basics of recruitment or care about the position that needs to be filled. For example, in IT recruitment, referring to expertise from a single technology stack is understandable, but to expect a software developer to be experienced in competing technologies like ASP.Net and PHP is ridiculous unless it is a consulting firm working in diverse technologies.
Company Culture
Good job postings should help candidates understand the corporate culture of the employing company. It should also vividly describe what it would mean to be working in such an environment. By being brief, recruiters should take care not to dilute the USP that makes the company special. Apart from getting an idea of the required skills, job seekers would like to know whether they would be comfortable with the company culture.
A job posting should be written so that it attracts the right candidate. By using the proper words, it should be able to identify the right candidates and reject the substandard ones.
