There is no excuse for ever arriving late for an interview -- other than some sort of disaster. Strive to arrive about 15 minutes before your scheduled interview to complete additional paperwork and allow yourself time to get settled. Arriving a bit early is also a chance to observe the dynamics of the workplace.
The day before the interview, pack up extra copies of your resume or CV and reference list. It is also important to bring a valid ID for your application. If you don't have a valid ID, an NBI clearance will do. Finally, be mentally prepared for the assessment and interview. Since you arrived early, just relax, focus and remember that job applications are just mind games. If you're prepared, you will land that post.
