Job posting (as well as the website where you place the job vacancy) determines who will respond to it in many ways. If you are conservative, diligent, demanding, and expect the same from the applicant, then any emoji and jokes should be removed from the job description so that the posting does not give false impressions (of course, you would not have any of them but in case a colleague drafts a job description). If it is totally opposite with you, and you are the part of the "young ambitious team" with an "active lifestyle" and a fresh look, and you prefer to be in a short distance with the customers, maintaining close and family-like relations, then make sure that the approach of your business is clear from the job description right away. Overall, write the job posting in the same manner as you communicate with the customers and the colleagues.
If you are looking for a fun and easy person, do not start the job posting with "We have been on the market since 1899". The person with the characteristics you are looking for will likely to skip the posting, as he will not be able recognize that the vacancy corresponds to his interests.
Once, I wrote the job description with all my heart, and made it clear that I was looking for the fervid and bright stars, unique snowflakes in the customer support. In response to the job posting, I received a pile of resumes from specialists with 10+ years of experience working with 1C and Excel. Therefore, it is important to choose a right website to place a job posting.
