Well, companies can't hire you if you don't apply. Do your best and make them all tell you no, rather than expecting it and not trying.

Just know that it's often not your fault your application didn't make it through. It's half an exhausting lottery. I've had pristinely written CV and letter with family and career counselors editing it not get anything, and applications where I found spelling mistakes after were interested in interviewing. Companies tend to have hiring seasons where if you apply at a consistent pace, you'll get no answers some months and many answers at other times.

Even recruiting itself is a hellscape, you see corps getting recruiters, laying them off because "they don't need em anymore", then all of sudden they need more staff but way more than the recruiters they have can handle.
