The job posting platform is very convenient and effective. All ads appear on the same day you submit them. You can easily verify this by visiting any of the sites in the database and finding your job listing. There are plenty of sites, more than enough. After receiving resumes, you interact with candidates on your own. It all depends on luck, as not everyone provides accurate information in their resumes, and not everyone answers calls, etc. This has nothing to do with the platform itself. However, the prices could be lowered a bit, as posting a large number of vacancies can get quite expensive.
