There is not a single best attire. Generally speaking, you should dress business casual, in a way that makes you feel confident and professional, but remembering that you will be doing a lot of walking. What would you wear if you needed to present a poster at a conference, or give a talk to your department? Wear that.</p>
<p>For the most part, professors will probably not be paying attention to what you’re wearing. A nice pair of pants will be fine. (For the record, I wore a skirt for all of my east coast interviews, and didn’t die. But a skirt is the only thing that I wear when I dress up, so YMMV.)</p>

Performing lab work, no. Interviews will almost always take place entirely in a professor’s office. But you could certainly be asked to outline a research project you’d like to take on, although that wouldn’t be a typical question.</p>
<p>Generally, you’ll just talk about your previous research experience, and the PI will talk about his/her research program, and you’ll have a chance to ask questions about his/her work or about the program. </p>

For some programs, yes. Acting like a jerk to the current students, or getting totally wasted at a student party, is not advised.</p>

The first day, people will arrive at different times and end up somewhere at the hotel or on campus. The first night is often a student-hosted dinner – maybe your student host will take you out, or maybe you and a group of prospective students will go out with a few current students. You’ll get some sort of schedule (or at least directions for the next morning.)</p>
<p>The second day, you will probably meet on campus and have breakfast with other recruits. You’ll hear some combination of student and faculty research talks and hear about logistics within the program. Some portion of the day will be blocked off for interviews. You’ll probably go to dinner with faculty members and current students, and there might be a student-hosted party afterward.</p>
<p>The third day, you’ll probably have more interviews. There might be student-led trips to introduce you to the surrounding town/city. And then you go home!</p>
