Google Intern interview questions

It was a phone interview. They asked me about my project and stuff. They wanted to build some signal processing tool and asked questions related to them. They also asked questions about structural dynamics. Then, they asked me questions about some hardware which I ddidn't know. They were very particular on Signals & Systems.
