Dressing appropriately for an interview is critical. The goal of a good job interview is to get a job offer. The interview is the last stage of your job search. It is the most vital prerequisite to getting the job. You have just received your first job offer.
Most employers still prefer a mailed resume on good quality resume paper to e-mailed resumes.
You should always research an organization before applying for a position. You should not discuss salary until the employer has extended an offer to you. An interview should be followed up with a thank you note within no more than 24 hours after the interview.
