In what areas are specialized HE less frequently required?

Question

Career in IT

I read, for example, that in Java they often require VO, because work is often related to business and finance.
If, for example, I want to become an android developer, can I offset the VO requirement with a couple of successful home projects? Would background in other languages ​​(php) help to get hired without VO?
In general, the question is - in which languages ​​and areas of programming is higher education more often required and where is it more difficult to overcome this requirement?
Thank you.

Answer 1

You just need to understand that higher education is needed to get a first second job, then its need can only be formal
