Google Engineer interview questions

first got an email from recruiter acknowledging the interest from google. Talked with recruiter over the phone for about 15 minutes, just general question "what kind of job you are having now?". Then recruiter set up a phone interview with an engineer. The phone interview lasted about 1 hour. The questions range from the work experience, the operating system questions to the coding questions.

Great company, casual working environment, free food, onsite medical and other convenience services. Five interviews. Programming, algorithm, data structure, software design, C++, Linux, Java, web technology, interpersonal skills. Think on your feet, walk through your thinking process, not all questions have one solution, some can be solved multiple ways, think outside the box.
