1.Application through western unión job board 2.email saying that I have to do a English test 3. Interview through zoom with the head hunter of latín América, normal question about yourself and your job experience

I made an online aplication, then I recieved an invitation to make an english test. After that, I scheduled a video interview with a HR associate outside Costa Rica. This video interview was very fast, which I didn't like at all. The woman who interviwed me, never looked me in the eyes, I felt that she didn't attention to what I was saying, at all; she was only "taking notes" at a computer like a robot. About two days after I recieved an email saying that I was not selected for the position, without any feedback about it. I would've like to know why they didn't chose me or, at least, what I need to improve according their criteria.
