How to learn it

No pick yet — Asked for mostly by research, inference and infra roles; picks come after the FDE and AI Engineer tracks.

A posting counts when its description mentions the skill in what the role does or asks for — the company's description of itself is left out. Shares are over technical postings only; the tags are checked against the postings every month and a skill below90% precision is not shown. How we count.
