I've had a few of these interviews. Some do it well by showing genuine interest and maybe they have expertise in the area and it's fun chatting about the project. Other's see it more like cross examination or make it adversarial. I personally get nervous and tense up when I feel attacked. Maybe it's a good way to opt myself out of working in those environments.

This is spot on. Having shadowed my share of interviews, I've found that the attitude of the interviewer is the biggest factor in having a good interview experience.

Making sure interviewers show genuine interest, and are open to different candidate background is one of the most difficult things to guarantee when you have many people interviewing.
