lol at the people saying "always wear a suit". Did you not read where the OP said it was a creative digital marketing agency?
I think for a creative agency where you know full well what the environment is like you could look a bit silly turning up in a suit. Maybe 10 years ago I'd have still said turn up in a suit anyway because it's an interview but I think potentially the impression you'd give if you did so is that you're a bit clueless. If you have a recruiter then ask them. If it is for a 'creative' role then I'd definitely avoid, if it for some business role then "smart casual".
This for sure. You'll look like a royal plum turning up to an interview like this in a suit (assuming the role is not part of the finance team, or an SVP+ role. It would definitely count
against you, as it shows a lack of experience in that sort of working environment. And lack of knowledge on the sorts of people you'll be working with.
If you wear a suit, whats the worst that can happen?
As above. You'll look clueless.
I've worked in the film industry for 11 years and have never worn a suit to an interview. Generally I would go with smarter casual boots (chukka/desert boots), good jeans, nice plain/smart shirt tucked in. Funnily enough all the interviews in my career have been on sweltering summers days so I've left it at that, but if you wanted to go one-up you could chuck a smart blazer/sports jacket over the top.
EDIT: I checked out my account on Thread and this is what it recommended for a job interview
I would stick with the smarter boot, and darker jeans personally.
