I applied for a position a few weeks ago where all of the candidates showed up wearing suits and had briefcases, myself included. The HR lady even commented about it. I thought a suit and tie was standard..
Odd, I NEVER carry a briefcase to an interview. I use a zipped leather portfolio: extra resumes, business cards, and a handy pad for taking notes.
But then, I’m a techie, not a management or sales type. . .
