Do take a practice run to the location where you are having the interview -- or be sure you know exactly where it is and how lone it taker to get there. Do you research and know the type of job interview you will be encountering. And do prepare and practice for the interview, but don't memorize or over-rehearse your answers. Do dress the part for the job, the company, the industry. And do on the side of conservatism. Do plan to arrive about 10 minutes early. Late arrival for a job interview is never excusable. If you are running late, do phone the company.
