Imagine you are searching through job postings. You’ve got a list and now you opt to sort by date, or location or other relevant category. Each column can be sorted. Typical options are some kind of logical progression. A job seeker might sort jobs to list the newest ones first.
I recently saw a job listing whose sort routine made sense only in theory. In practice, the result was neither sorted nor logical. However you sorted it, the list was a sorted mess.
Here’s what the date sort looked like:
Here’s a rule to break; don’t sort dates numerically or alphabetically. Who cares about a group of jobs that were posted on the 27th of every month. Not useful. In the context of a job posting, a date must be sorted chronologically.
