Subject: Interviews - your tips

My tips would be:

• do your research / ask good questions
• be yourself
• relax
• smile.

I second JohnOliver's recommendation to ask good questions.  Nothing shows you are more interested in the organization than asking questions that show you've read the website, talked to others, and are looking at the meat/heart of the work/position.

On the other side of the interview, asking questions that would require the interviewee to have read the website (at least) or have a general idea/opinion of the sector will help separate the pack.

I agree with the other comments but it can be hard sometimes to find good questions to ask.  You are usually asked at the end of the interview - when the interviewers have asked all their questions - if you have any.   It can help to ask questions during the interview when queries come up naturally.   Some good questions I've come across include asking about the organisation's plans for the future, budgets for a particular area, the outcome of an activity/event - rather than questions about terms and conditions or pay.         

I have some don'ts. Don't turn up late. Don't think that you know it all. Don't think that it is your right to get the job.
