How can we verify real government jobs and schemes in Pakistan before applying?

There are many websites that share updates about government jobs, schemes, admissions, and career opportunities in Pakistan. However, it can sometimes be confusing to know which announcements are official and which ones are outdated or unofficial.

While searching for updates, I came across jobscentre.pk, which lists different opportunities across Pakistan. My concern is how to properly verify whether a job or scheme is officially announced by the relevant department.

Should we always cross-check the information with the official government website? Is there a safe way to confirm that an online application portal is genuine? I want to avoid fake job advertisements and make sure I only apply to authentic programs. Any guidance from experienced applicants would be helpful.
