The dress code, does it affect on the interview ?

Not at all. Attitude matters bro.

Cheers !

Yes,  I believe even the simple things like the way you enter  the interview room or how you greet the interviewer will give an impact. How you dressed up and Groomed your self during the interview could say a lot about your personality  its also a way for them to know if your really eager to be interviewed. Dress Smart and Prepare well. =)
