Poor stats in getting replies is almost always due to having a poorly written CV. Did you try having your CV to someone who does hiring?

As for getting a degree, most things in recruitment are actually signalling(as in asymmetrical information).

The languages you learn and use during your studies is mostly irrelevant.
