The same job advertisement had already been placed five weeks ago, whereupon I applied by sending complete documents by e-mail, I received a reading confirmation.
No answer, three weeks later I send a friendly reminder by email - again no answer.
Well, even if there is no interest in an interview despite the best qualifications, probably because of my age, it is a question of politeness and dealing with each other, at least to get a short refusal or any answer at all, dear Mr. Managing Director.
