In my opinion, the article question "If you were a piece of furniture, what would you be and how would it benefit the company?" is most difficult for me to answer. How can you convey what you are all about by comparing yourself to a lamp or a toaster? I understand that the purpose of the question is to get you to think on your feet, but I don't like this question.
I would say that the #1 issue with employees is becoming an expert after with no need to learn or take advice after the first day. There are lots of common excuses that employees use frequently, but I feel that lots of people are too stubborn or cocky to take advice.
For my chosen profession, business attire is most appropriate for an interview. A pencil skirt or slacks with a nice top and possibly a blazer or jacket with heels or flats is pretty much standard for professional work attire.
Communication, attitude, job qualifications, and appearance are the top four categories that employers look for when they interview you. I think that attitude is the most important category for employers when they interview you. If your attitude is poor, then they will not even worry about how you communicate or your qualifications for the job. I think that appearance is next, then communication, then qualifications.
