Before the interview, consider how you will be dressed. Appearance and demeanor are of great importance and practically determine the first impression. If you are going to an interview at a financial institution, wear conservative business attire. If you are going to an interview with a construction company or design firm, you can afford to dress in a more casual style. You can try to find out in advance whether the company has adopted a business or more casual style of clothing, but in any case, it is better to dress more formally for an interview. If showing up to work in jeans is considered par for the course at this firm, you will be able to afford it when you start working, but you should not come to an interview in a sweater and jeans. In any case, you should look neat and tidy. Women have a much wider choice, but the more mistakes they can make in doing so. It is best for a woman to wear a formal suit or a fairly conservative dress for an interview, without going to extremes when choosing the length of the skirt, colors and jewelry. Do not use harsh perfume or cologne.
