You feel confident the interview will go well, because you both speak English. English as a mother tongue and English as an adopted tongue are not the same language. If you're a native English speaker and you forget this important fact, you can come away from an interview with a non-native English speaker without the precise information you need. Not to worry, though. Here are ten steps you can take to make sure that nothing gets lost in the translation from your English to theirs.
Consonants really count.
Also avoid adding consonants where they don't belong. To a non-native English speaker, these can be truly foreign words. An excellent pre-interview exercise is to make a recording of your voice, either speaking with a friend or reading a text or your interview questions aloud. When you play the tape, listen for the places where you run words together or blunt your t's and d's, for example. Not only is there a chance they will not understand you, but they will also likely lose confidence in their own ability to communicate with you.
