I it sounds obvious, but you really must prepare before the interview. Prepare your questions in advance. Think about the order you will ask them. A rule of thumb is to ask questions about facts first, leaving opinion questions until later. Most people find questions about facts much easier to answer, so they start to feel more at ease.

Try to interview the person in a place which is appropriate to the interview – their place of work, for example. Interviewing a person on their territory can put them at ease, and also provide you with colour for your story.

How you start the interview can influence how successful it will be. Set your ground rules. For example, you may want to insist that the interviewee says in advance if they want what they say to be off the record.

During the interview, you should be polite but firm. Use your list of questions as a base for the interview, not a rigid script. Ask for evidence to support any claims made by the interviewee. Don’t be afraid to ask ‘How do you know that?’ But never ask leading questions. Let the person say what they want to say, not what you want them to say.
