Why should you dress professionally and do some research beforehand? you should dress professionally, but research is not needed. dressing professionally and doing research you appear confident and competent. you should research, but dress as usual to them learn who you really are. if you don t do both of these, you will not even be interviewed.?

I believe the answer is: . Dressing professionally and doing research help you appear confident and competent.

Dressing professionally would improve how you feel about yourself and the first impression that your employers and clients have towards you.

Doing a research before coming, would familiarize yourself with the situation that your employers or clients have. Understanding their situation without being explained to with make you seem smarter and more competent compared to other candidates who don't do it.
