My best guess is that the WT writer was just lazy, or sloppy, or both. I would guess that the "job offer" was for the girl to leave Ethiopia and accept a job in the European Union. A wage of 3000 Euros per month is either pretty good or at least average, depending on which particular country the job was in.
It would still stretch the bounds of credulity. Why would anyone in the European Union offer an obscure, uneducated Ethiopian girl a job that paid 3,000 euros/month? What exactly was she so qualified to do without any "higher education"? And as already mentioned, no one is "offered a a scholarship" no matter what your grades are. You have to apply for it. I think it's fair to say that this was not just the Writing Department being 'lazy' or 'sloppy'----they simply told an outrageous lie made up from a ficticious character with an unrealistic and absurd setting and have tried passing it off as a wonderful example of Christian financial martyrdom.
