Google Software Engineer interview questions

I've got 2 phone interviews in a row by a reference. Then they invite me to do an onsite interview. There are 4 individual technical interviews from 9:45 am to 2:30 pm. Lunch interview doesn't count for reviews.

They take on-campus written and shortlist candidates from it. They also seek good academics for shortlisting criteria. There are 5 rounds of Interviews in Google . If you go through all , you have fair chances of selection. They call you at their office for interviews (all at their expense) the five rounds can be in any order and every round is shortlisting round after first two interviews. They basically check your skills in various domains like Data Structures , Algorithms, Coding , Designing, Projects you have done and much more. They start from basics and move to extreme difficult questions. Every round is of fixed time 45-50 minutes. They see your thinking process not the solutions for difficult questions. Just give your best and involve your Interviewer during solving your problem.
