It's kind of "offense is the best defense" method.
I haven't done many interviews, but I found a good strategy is to have some questions about the technology the company is using. Then you can both show interest and turn the interview on the head, instead of them asking you technical questions (for which you might not know the answer), you ask technical questions that show you have done some basic research and have basic understanding.
I have used a similar strategy on some oral exams at the university.
Many people (especially specialists) are not natural examiners, and are delighted to talk about their field with someone who has some understanding of it, regardless of the fact that they should conduct an interview or exam.
But then again, it takes a certain type of character to do it (since I am a curious person, it comes somewhat naturally). You can't really fake it, you have to put in some effort of learning about the technology in question in advance.
