Lots of good advice here.

Do you know anyone who has done hiring who could help you practice? I've been on both ends of the process and practice helps. Keep in mind that interviews are as individual as the people doing the interviewing.

Try to put yourself in the interviewer's shoes, and imagine what questions you'd ask if you were looking at your resume. How would your technical skill-set help their organization? How would your "soft skills" help -- your capacity for teamwork, your work ethic, your drive to succeed and contribute?

Everywhere I've done hiring, what I'm looking for in the interview is a sense of the person and answers to any questions the resume poses (such as clarifying what exactly they did in those jobs and looking for an explanation of gaps between jobs). Some tips:

1) SCRUB YOUR RESUME and have others do so, too. Make sure there are no errors. Your resume is the first clue to your "attention-to-detail."

2) BRING COPIES OF YOUR RESUME TO THE INTERVIEW. In case the interviewer misplaced it, they'll appreciate you having extras handy.

3) No matter what, follow up the interview with a typed THANK YOU NOTE. This alone will set you apart from the crowd -- especially these days. E-mails are no substitute for old-fashioned snail-mail, even in IT. And if you aren't the right fit for this job, the thank you note will make it more likely they'll keep you in mind for the future.

4) ASK STRATEGIC QUESTIONS. A good interview is a two-way conversation. You are also interviewing that workplace. Know as much as you can going in to the interview and plan beforehand a couple of questions that show your knowledge and demonstrate your strategic sense (including who else you'd be working with and how long they've been there -- a team player wants to know about their future team).

5) INVENTORY YOUR STRENGTHS -- and have them on the tip of your tongue. Your technical qualifications, past successes, personal attributes (teamworker, hardworker, quick learner)

6) BE ABLE TO ARTICULATE A WEAKNESS -- I never ask this question but it is not uncommon. Can't say I have a stock answer but would try to formulate in advance a weakness that also conveys a strength. (perhaps the ETS gang can help with this)

7) Be rested and try to be relaxed when you go in. Give it your best shot and know that even if that situation doesn't work out you can gain from the process.

The interviewer wants you to succeed. They want to like you and know that you can do the job so they can hire you and get on with their own job.

Have faith.
