Rejected. Now what? This is what makes the difference.
A rejection isn't the problem. The problem is often what happens afterwards, or doesn't. Over the years I've seen a clear difference between people who pick up speed again quickly after a rejection and those who are stuck for weeks.
The first difference: allow yourself the disappointment, but with a clear deadline. One evening of frustration is healthy. Two weeks of brooding cost you energy you need for the next application.
The second difference: take exactly one insight from every rejection, not ten. Maybe the cover letter was too generic. Maybe a question came up in the interview that you had no good answer for. Take that one thing with you and let go of the rest.
The third difference: keep things running in parallel instead of pausing. If you stop all other processes after a rejection to collect yourself, you lose twice: time and momentum. Better: keep at least one new application going every week, no matter how the last one turned out.
And the fourth, often underestimated difference: send a short, friendly reply to the company, even after a rejection. It costs you two minutes and keeps a door open that may open again when another position becomes available. I've brought candidates back a year later myself, just because the goodbye was professional.
