A job interview proves to be challenging when carried out in your native language, let alone in a foreign language.
Here is the first part of most popular questions regarding Work History: previous employment, responsibilities and activities you've been involved in since your last employment (in case you're unemployed at the time of interviewing for the job).
Note the vocabulary used, linking words, grammar in use and practice answering the questions for yourself. Think of the best way you can deliver a detailed account of your previous employment and the way it relates to the new job.
