I think that's relevant if you have a highly specialized skillset like embedded Linux. People don't make embedded Linux job postings to "test the waters" or "see if the perfect candidate applies." If the listing is up, they're probably hiring an embedded Linux developer, and while there will be a lot of resume frauds applying, they actually need to make the hire.

If you're applying for a B2B SaaS product manager job there are 50,000 jobs and 200,000 applicants and it's a completely different situation.
