The most significant thing to consider when you're dressing for a job interview, regardless of the position, is that you must dress to impress by looking professional. Your interview attire depends on the job role you are applying for, so before choosing what to wear it is always a good idea to research the company in order to determine the dress code.
Even if you still can't understand the dress code here you can find the best interview outfits for men and women:
Professional/Business interview attire:
If you are dressing for a job interview in the corporate field (e.g. banking, law, finance, insurance etc) then you need a formal outfit. In general, this means a suit and tie for men and a skirt or pantsuit with heels for women.
Suit in a solid color such as navy, black, or gray
Long-sleeved white shirt or in any other color that can be matched with the suit
