Don't cause unnecessary stress by concentrating on negatives.
Keep wording professional at all times.
Arrive on time, so you're relaxed and prepared for the interview.
Don't just recap your CV. Use this chance to show all your qualities that a CV does not visualise.
Make good, first impressions - be polite with everyone you meet. Offer a firm handshake.
Take deep breaths, relax your face muscles, take 5 minutes to pause before the interview.
Don't brag too much. Humility is powerful.
Job Hunting Tips:
"Your CV will not earn the gig on its own. Its 'job' is to earn an interview. Make sure your CV will arouse the employers’ attention so that you can get the first interview - and then that is where you can earn the job."
