Are there other major economic sectors which have circled the wagons around making job applicants do remedial coursework as live performance art?
This is largely a result of low barriers to entry into the profession. You do not need to have a qualification from an accredited institution to be a practicing software engineer/programmer/developer. Unlike doctors, lawyers, dentists, civil engineers... So you have a well paying profession, hot demand, good working conditions, and no external framework to ensure a base level of competence. Of course people will try…
As I shifted into tech, the hiring process didn’t surprise me but for the wrong reason. All I learned was software engineers put up with similar bullshit to lawyers!
All that said I don’t know how to fix any of it easily. Maybe no one else does either, and so here we remain.
