Things are a bit sketchy at the moment. Had a recent get-together including a former co-worker who was an obvious hire-this-person. They got hit in a layoff and they're still essentially out of work after a year.

Job postings that don't respond to inquiries about the role are a waste of your time, and it's possible to spend all day every day applying to them. Job postings without a method of contact are probably some kind of scam.

The easiest step, IMHO, is to start by ignoring employers who use a service to filter applicants.
