I would call it “for want of reasonable hiring and onboarding processes”. How does someone get into a data engineering job without any knowledge of SQL and doesn’t even get basic onsite training?
Largely due to the fact that "Data Engineer" is defined differently at every company. Some want a SRE, some want a Database Architect, some want a software engineer that knows some SQL, others want only SQL junkies.
As a result, I have picked up a variety of skills to fit into whatever my company dictated what a Data Engineer should handle
