    Google hiring process

    There is a lot of mystery and misinformation about the Google hiring process. The Google hiring process is designed to hire the most talented, creative, and articulate people in the world who will be the best fit for Google.Google receives over one million resumes per year, and hires more than thousands , depending on economic conditions

    Google hiring process: The hiring process is pretty standard, it is the evaluation that is different. All open jobs are listed on Google.com. Browse for a job that fits you and submit your resume online. Every resume submitted online gets reviewed

    Google Resume Screen:

    In the first step of the process the recruiter screens every resume for technical requirements, education, and experience to make sure there is a potential fit. If there is no fit you will get a polite “no fit at this time” response, but your resume will be kept on file. The recruiter really does look at existing resumes on file when a new job req opens up. If there is a fit, a recruiter will contact you to set up a phone screen interview.

    On line Test and Telephonic Interview
    Google recruiter will contact you explain the process, and let you know what to expect. The phone screen is usually done by an employee in a similar role, and usually takes 30 minutes. There could be two or more phone screens, and you may even be asked to write code in a shared Google Doc during the phone screen if this is a technical role. The goal is to further assess your technical skills, past experience, and motivation for this new role .Google conducts one line Your responsibility to check your mail regularly with out fail because nobody calls you

    Interview : Google site interview The first on site interview will be with four or five people for 45 minutes each. This interview will go deeper into your technical skills or domain specific knowledge. If this is a technical role you will be asked to solve technical problems in real time, which may include coding a solution or white-boarding a design. This can get pretty intense for the unprepared candidate, or incredibly fun and stimulating if you are into it. Every interviewer submits their feedback in a standard format about the candidate and assigns a numerical ranking to the candidate. The feedback is reviewed by the recruiter and compared to feedback on other candidates for this job and similar roles. There is also a process to collect feedback from former colleagues. All existing employees resumes are in a database. Hiring Committee-The committee reviews every piece of feedback as well as the resume and work experience.

    Some Interview Questions

    Google Interview Questions: Product Marketing Manager


    1) Why do you want to join Google?

    2) What do you know about Google’s product and technology?

    3) If you are Product Manager for Google’s Adwords, how do you plan to market this?

    4) What would you say during an AdWords or AdSense product seminar?

    5) Who are Google competitors, and how does Google compete with them?

    6) Have you ever used Google’s products? Gmail?

    7) What’s a creative way of marketing Google’s brand name and product?

    8) If you are the product marketing manager for Google’s Gmail product, how do you plan to market it so as to achieve 100 million customers in 6 months?

    Google Interview Questions: Product Manager

    1) How would you boost the GMail subscription base?

    2) What is the most efficient way to sort a million integers?

    3) How would you re-position Google’s offerings to counteract competitive threats from Microsoft?

    4) How many golf balls can fit in a school bus?

    5) You are shrunk to the height of a nickel and your mass is proportionally reduced so as to maintain your original density.
    You are then thrown into an empty glass blender. The blades will start moving in 60 seconds. What do you do?

    6) How much should you charge to wash all the windows in Seattle?

    7) How would you find out if a machine’s stack grows up or down in memory?

    8) Explain a database in three sentences to your eight-year-old nephew.

    There were multiple objective questions and a single coding question. The focus of the paper was how quickly you could solve the general ability questions. The time limit was 1 hour.

    The written test had 3 objective question sets and 2 coding question. Instead of fixing marks for each question, they had given a weightage estimate by giving suggested time interval for each question.

    All objective question were given 1 min each, 1st coding question was 30 minutes and the 2nd question was suggested 45 minutes. All questions were just given estimated time intervals, and the entire paper was given at one go, with a total time of 1 hour 30 minutes.

    Although the function prototypes for the coding questions were given with STL containers but you could use any language that suited you. Obviously using C++ STL or a similar construct in other languages such as Java was appreciated.

    For each of the coding question an optional space was given for writing the logic. Although the logic was optional, but we seriously recommend you to give your logic. It makes much easier for the checker to understand your answer and increases your chances.

    Subjective Questions

    1 Write a program to find the index in an circular array such that the string that is formed starting from that index is first in lexicographic order. For example in the circular array ABCDEABCCDE

    2 You are given an array of n elements [1,2,....n]. For example {3,2,1,6,7,4,5}.

    3 Now we create a signature of this array by comparing every consecutive pir of elements. If they increase, write I else write D. For example for the above array, the signature would be "DDIIDI". The signature thus has a length of N-1. Now the question is given a signature, compute the lexicographically smallest permutation of [1,2,....n]. Write the below function in language of your choice.

    42. What is the optimal size of a project team, above which additional members do not contribute productivity equivalent to the percentage increase in the staff size?
    A) 1 B) 3 C) 5 D) 11 E) 24


    43. Given a triangle ABC, how would you use only a compass and straight edge to find a point P such that triangles ABP, ACP and BCP have equal perimeters? (Assume that ABC is constructed so that a solution does exist.)
    This is the isoperimetric point , which is at the center of the larger Soddy circle. It is related to Apollonius' problem . The three tangent circles are easy to construct: The circle around has diameter , which gives the other two circles. A summary of compass and straightedge constructions for the outer Soddy circle can be found in " Apollonius' Problem: A Study of Solutions and Their Connections" by David Gisch and Jason M. Ribando.
