how to introduce myself in the interview.

Now I am going to quit my work. l love to engaging in foreign trade for English, but my English ability is limited. What can I do? How do I introduce myself in the interview? I think I am good at reading and writing, but my listening is poor because I cannot speak out confidently and I have a slow response.

Once you understand the basics, it is absolutely critical that you engage in conversation, preferably with native-speakers. That way you will practice listening and responding until you begin to "think" in your new language and are no longer trying to translate twice for each exchange. There is no substitute for practice.
