Notice the amount of detail necessary when you are talking about your experience. One of the most common mistakes made by foreigners when discussing their former employment is to speak too generally. The employer wants to know exactly what you did and how you did it; the more detail you can give the more the interviewer knows that you understand the type of work. Remember to vary your vocabulary when talking about your responsibilities. Also, do not begin every sentence with "I". Use the passive voice, or an introductory clause to help you add variety to your presentation
