I don’t know where to start for a job interview

Student: I don’t know where to start for a job interview in America because the system I use is only Russian.

Teacher:  Get comfortable with the terms in English so you can easily explain what you do in English.  This is going to require a lot of reading, both about the system itself  (in this case: 1C: Enterprise 8 )  and then general IT interview questions.

Interviews require a lot of research.   You need to know exactly what they are looking for and explain how you fit their needs.  You also need to know about the company and their practices.  In the IT industry the required skill set may be the same, but how the companies operate vary from one to the next.   You need to find out how they operate and make sure that your answers fit with how they do things.
