NetLogic Microsystems Applications Engineer interview questions

Applied online and got an email from an senior engineer to schedule the phone interview. It was an 1.5 hour interview. First half was about past working experience, second half were some technical questions. Technical questions started out to be very basic, like defining XOR gate, NAND gate, etc., then it went on to designing multiplexers with given gates. The interviewer had a very heavy accent which made it very hard for me to understand his questions.
