I need help to pass a job interview in English

In my country, there are some companies called, "call centers". To work there, you need to pass an interview in English, but I have some problems with my listening skills and my pronounciation. If someone wants to help me please send me a messagge. I can teach you Spanish, everything about Spanish.

I'm not sure if you wanted this corrected, so sorry if you didn't!

No estoy seguro si quieres esto escritura corregido, lo siento si no quisiste.
