Google Programmer interview questions

I met with the hiring manager, a nice guy. We discussed programming and my history as a programmer, including my capabilities. It was pleasant and cordial and I thought I would get the position. There are many great programmers out there so you can imagine how competitive it is to get a spot at google. I went through two interviews and I received a call the next week and was informed I wasn't getting the position

two rounds of phone interviews, and another phone interview.
