@sumek While remote jobs are surely popular, this is of course, not reliable data. Anyone, anywhere can apply to a job posted on LinkedIn with a click.

One anecdotal — and therefore also not entirely reliable — account: when I post jobs on LinkedIn, I find most of the applications are garbage from applicants that do not meet the minimum qualifications. This is so common that LinkedIn filters out such noise by default, though one can see the filtered out applications if desired.
