    Phone interview: The Interviewer was late for 20 mins... Ask nothing on my resume. Tow questions: 1) A string consists of ‘0’, ‘1’ and '?'. The question mark can be either '0' or '1'. Find all possible combinations for a string. 2) Give you a text file, remove duplicated lines. Follow up: If the file is very large, general hash map takes too much spaces, come up with a better solution.

    Difficult Interview

    Application

    I applied through a recruiter. The process took 4+ weeksinterviewed at Google (Mountain View, CA) in March 2015.

    Interview

    First there was a technical phone interview, with a fairly straightforward programming problem using Google Docs to write on. Then I heard back to schedule the onsite portion. Flights and hotel are paid for, and they're rather flexible to work with your schedule. The onsite interview was 4 technical questions with lunch after the first two. All the questions are fairly difficult, they skip right past the easy ones and only talk briefly about your resume and experience. Definitely know big O notation and be able to calculate the time complexity for any code you write. A lot of problems involved graphs or matrices, but involved other data structures as well. They give you a full list of what you should know beforehand, and much of it will be covered.

    Interview Questions

    • What is the time complexity of your implementation? What is the space complexity? Can it be done faster? Can it be done with less space? Write a new implementation doing both.   Answer Question

    I were scheduled three interviews back to back, each takes 45 mins. The interviewer were nice and inspiring. They gave advice on my code. Firstly I was asked to write code for a simple solution. After I finished, the interviewer followed up, including asked me what the corner cases are and how can I improve my solution. They are highly technical and helpful.

    Difficult Interview

    Application

    I applied through a recruiter – interviewed at Google.

    Interview

    Hiring process starts with phone screen. Once you are through it, you are called to Google head quarters in Mountain View, CA. Here I had 4 rounds of interview and a lunch break in-between. They book tickets for your travel and hotel and reimburse your expenditure during your stay. I must say Google HRs are really helpful in making me understand entire interview process and giving suggestions for the same.

    Interview Questions

    • None of the questions were unexpected, Be sure you know data structures like Maps, Trees, Array/Lists well and Time complexities. They usually ask time complexity of your program in the end of the solution u gave. Even read about OOD and be thorough. Again, its Google so make sure you prepare our best :)   Answer Question
