I went to an interview today, unexpectedly, they handed me a test with questions pulled from the 70-291 exam. Now, I don't know how well I did because I had to guess some questions. The test had 20 questions in MS ( long paragraphs) format and I had 15 minutes to finish. They also brought in 2 guys from the IT department to ask me questions. All questions were on DNS 75%, Subnetting15% and Exchange10%. Interview lasted about 2 hrs.
