ICT is of course absolutely right to point out that this industry massively favours experience above educational qualifications.
Educational qualifications are very nice to have, and in many cases a minimum standard is essential to get your foot in the door. But, to get the most attractive jobs (often any job at all), it's your experience within the industry that matters far more.
It is certainly possible to get yourself labelled as unemployable because you've spent your whole life in educational institutions and appear to have actively avoided engagement with the real world.
