I think you hit the nail on the head. I only have a BA and it's only in English.
That has to be it.
You said you apply weekly, since October.....and as someone else pointed out, in an industry where hirings are most likely done internally.
You've gone 6 months, applying only once a week, where with maybe only 10% of those jobs external applicants are considered, let alone even looked at.
Try applying 100 times a week
