I have an interview this week which I am assuming will be quite formal, financial services, customer facing etc. I'm just not sure what is required to be worn for a formal interview? I had thought a smart blouse/ trousers or a smart dress but having looked at their website people seem to wear more formal things than this.
What should I wear, assuming it is formal, and how important do you think it is that I get it right? If I'm a bit off will it really count against me? I'm an over thinker and am starting to panic.
