An exercise on data-job-postings

An exercise worth doing on data-job-postings.

3,500 rows, 11 columns, one row per posting. Thirty-five hundred data job ads with titles, seniority, location, remote policy, salary bands, and a pipe-delimited skills column that needs parsing before it is useful.

Every dataset here is synthetic, which is a deliberate trade. It costs realism and buys three things: we can ship it CC0 with no licence trap, we can bake in the exact quirk a lesson needs, and nobody's real records end up in a tutorial.

Something to try: Compare remote versus onsite pay, holding seniority and city fixed. The SQL playground has it loaded already, and the data explorer will profile every column in one pass if you would rather look before you query.

select *
from data_job_postings
limit 20;

The file is generated from a fixed seed, so the CSV you download today is byte-identical to the one from last year. That matters more than it sounds: it means a lesson can say "row 412 is the interesting one" and still be right in eighteen months.
