Confession: I used to be a certificate collector.

Course completed — screenshot. Webinar attended — badge. Another PDF into the folder called "Career" that no recruiter will ever open. It felt productive. It was mostly decoration.

Then I noticed something about how people actually get hired, and it changed how I spend my study time.

The difference between proof of attendance and proof of ability

Most certificates prove one thing: you were present. You watched the videos, you clicked next, you passed a quiz you could retake unlimited times.
