Get there early! When I got there, they'll have you wait on the bench til you get called up for the 1st interviewer. They'll inform bout the job position you applied for and have you sign papers. Plus, you have to answer questions. When you're done with the 1st interviewer, you'll go back to the bench and wait til you're called up for the 2nd interviewer. Same process with this one, but different questions (easier than the 1st interviewer in my experience). When you're done, you'll go back to the bench where you'll get called up by some team leader and sign the final papers of the job offer (if you got the offer of course).
