Getting rejected during a job search sucks. There's no sugar-coating it. But treating rejection like a debugging session instead of a personal failure changes everything about how you approach your job search.
In software development, we don't take bugs personally. A failed test doesn't mean we're bad developers — it means something in the system needs fixing. The same logic applies to job rejections: they're data points that help you optimize your approach, not judgments on your worth as a professional.
