company, and have 3 interviews already in just a few weeks?

First, congratulations on being so dang efficient!

Second, I would dress up slightly if I were you. I like the suit jacket, collared shirt, with no tie look myself.

If you have a sec, let me in on any tips for finding a job that quickly. I'm also an IT professional looking for a job, and all the companies I'm seeing that are announcing jobs are moving at a snail's pace to fill them right now.
I'm in Utah.
