What skills did you learn on the job this past year?

What skills did you actually learn on the job this past year? Not from self-study or online courses, but through live hands-on training or genuinely challenging assignments.

My hunch is that learning opportunities have declined recently, with many companies leaning on “you own your career” narratives or treating a Udemy subscription as equivalent to employee training.

Curious to hear: what did you learn because of your job, not just alongside it?
