Asking about the human experience, I prefer to put the question so that more could not figure that a candidate knows, and that what he was dealing with in their work. If you have several candidates for the vacancy, the most convenient - is to ask them the same questions, so you can compare their answers.
It is important to assess the human resume, well, if you have it. Carefully read it before the meeting. If there are questionable or unclear point, ask about them. For example, if a person is left with a promising high-paying job at a lower position, find out the reasons why he did it.
During the interview, you should do everything to create a relaxed atmosphere for conversation. Negotiating with the candidate when he should come, find out what time the person will be comfortable. Take a talk at least 30 minutes of time. When a candidate will be politely greeted him, introduce yourself. Do not force a person to wait, immediately begin the interview. If you understand that he is nervous, do not just think that it is unsuitable candidate. It is possible that people just really want to work in your company. In that case, ask him that preceded his current situation, about his past positions, time of study. Listen carefully to the person, do not interrupt him.
Be kind. Formulate questions so that the candidate was forced to respond as you expect. If something you do not like the answers, you do not express your disapproval directly to the interview. During the conversation, use only approving comments.
When the interview came to an end, clearly tell the applicant. When he leaves, immediately write down impressions of him. If you think about the decision later, that such records can be of great help to you.
