Job ads full of typos, misspellings, grammar errors and poor formatting, such as chunks of jumbled text, look sloppy and reflect a place that doesn't value professional communication skills or care about producing audience oriented content.

Job ads that appear to be recycled postings that were haphazardly slapped together a decade+ ago but never updated since, hint of bloated bureaucracy and stagnation.
