Interview "Style"Speaking as an HR professional as well, the real answer is "it depends." Consider the following thoughts:
1) High end establishments are very "look conscious" A suit and tie and coming prepared with: "oh, please give me a few moments to change as I have my whites in my car" is a very positive 'best of both worlds' assuming that they asked you to prepare something.
2) Do you think when a doctor goes on an interview he / she shows up in scrubs?
3) Auditions work well, when actors show up fo the part -- but I yeild again to: it depends.
4) It's always ok to proactively ask the person setting up the interview to guide you -- we are stressed enough with the prospect of a new job, why add to it by worrying about attire? Just ask them? Sometime you'll get: "hey, it's up to you" that's when I'd show up in a suit (or shirt /tie depending on the job) and if they ask you to cook, again, be prepared to change. (It's my opinion, that you are 'dressing for the role' of interviewer, then possibly a chef...)
5) One more thing... Suit: CLEAN, PRESSED, POLISH. YOU: CLEAN, PRESSED, POLISH. Whites: SAME.
Again, image -- be prepared. :chef:
Hope this perspective helps.
