Most people read a job posting only to check if they qualify. That's the least useful way to
read one if you're trying to spot where things are headed. Companies write postings based on
what they need right now, and right now is often 6 to 18 months ahead of when that need
becomes common knowledge.
- Read the "nice to have" section as a preview. Requirements listed as preferred rather than required are frequently the thing that becomes a hard requirement across the industry a year or two later. It's an early, low-stakes signal companies are testing for.
- Look for unusual skill combinations, not single skills. A single in-demand skill is easy to spot and quickly saturates. A specific combination showing up repeatedly across postings, especially an unusual pairing, is a much narrower and more durable signal.
- Compare the same role across companies in the same window of time. One company asking for something unusual might just be one company's quirk. Three or four unrelated companies asking for the same unusual thing within a similar timeframe is a real pattern.
- Track a specific role or company over time, not just a single snapshot. Save postings periodically and compare them months apart. Watching how the requirements shift tells you far more than any single listing does on its own.
This applies just as well outside of full-time roles, freelance and contract postings show the
same shifts, usually even earlier, since companies test emerging needs with short-term work
before committing to a permanent hire.
