Perhaps it helps you to look at those interviews from a different perspective. Since you would have to spend some time with the company, you have the right to ask questions too. Turn the interview into a discussion. At least for me this is much more easy to handle. For example, instead of waiting for a question to test your knowledge about their language of choice, you could ask them whether they use it this or that way and mention your level of experience. If they still ask the question and you do not know the answer, you can at least say 'nope, no clue what you are talking about', without the feeling that they only know what you don't know. If possible make some educated guesses about their infrastructure and ask questions that reflect that you did your homework. Already said, but important enough to repeat: Be honest. If you are nervous, tell them. If you do not know an answer, admit it. If you are not sure if you understood something, ask again.
