I would consider myself a pretty good interviewer. I'm also happy, friendly, confident. I dont let myself get put off if it seems like the person interviewing me is a little standoffish. I take my time, dont feel rushed to get everyhting out in five minutes. I don't think that Im competing with anyone else for the position, and i remind myself that im interviewing THEM just as much as they are interviewing me. I try to imagine myself walking into that office every day for years and decide if thats something Im excited about or not.
I try to tell myself that the person interviewing me is really a good friend that I haven't seen in a really long time, and we're catching up on all the great things I've done since I've seen them last. For me its easy to talk about my work experience and my education. Its something I've worked hard for and something I've really proud of, so why wouldnt i want to talk about it for 30 minutes? In my mind i KNOW im the best person for this position, and im confident that once the interview gets to know me they will think so to. (For me its all about psyching myself up!)
Of course I've also got in the back of my mind answers to all those tricky questions, and specific examples of how I've demonstrated leadership, or some other relevant quality.
Oh ya, and I always find ways to say “our company”, “our financial statements”, basically I talk like I've already been working for the company for years and have identified myself with their company. I think pyschologically that if I make it seem like Im already a part of their team, then they will think so too and it makes it almost a no brainer for them to hire me because im already part of the team. This TOTALLY worked at an interview once, and the controller started going on and on about how “we” would be working together on doing this and this, and “we” would be closing the books pretty soon and I could do such and such. Pretty soon he was saying “we” and making plans on what I would be doing and I was still interviewing so technically he hadnt even hired me yet!
