Pass The Resume Screening

My virtual on-site Google Interview Experience | What is it like to do a virtual technical interview

The first part of Googles hiring process is, similar to most corporate jobs, resume screening. In this round, recruiters will screen your resume for technical requirements, education, experience,.. to make sure youre a potential fit.

Although hiring criteria depend on roles and company, the fundamental principles of writing winning resumes at Google is almost identical to writing winning consulting resumes. There are three fundamental rules you must apply in your resume:

Using professional, structured, and to-the point language implicitly shows screeners that youre a good communicator. Highlighting your achievements with explicit numbers and good structures also save screening time and leaves a good impression.

Before moving on, I highly recommend you checking out my consulting resume overview and specifically look at the resume examples I corrected to see how these rules can supercharge your resume.

What Interviewers Are Looking For

We are not simply looking for engineers to solve the problems they already know the answers to we are interested in engineers who can work out the answers to questions they had not come across before.

The above thing is the most important thing the interviewer will be looking for also read the below points

  • Interviewer have generally a mindset while taking the interview that if he/she can work along with the candidate in his/her daily to a job or not so do not show signs of arrogance or ego while giving the interviews.
  • Interviewers will check whether youve used the suitable data structures and algorithms while implementing the code or not.
  • Interviewers will notice the approach that how you optimized the solution, your knowledge about the choice of programming language, your coding speed, any corner cases that you missed and how you analyzed time and space complexity.
  • They will check how you communicated your thought process to solve a specific problem in a logical way. They will also check if you were able to catch the hint and was able to proceed with the solution or not.
  • Learn to think out loud during your whole interview otherwise interviewer will have no clue what you are thinking. Show your interviewer your thought process about the problem and what approach you are going to follow to solve the problem.
  • Practice by writing code on paper or whiteboard. It will really help you during your interview.
  • The Google Onsite Interview

    The Google onsite round involves speaking to a number of Googlers. Usually this will include four to six separate interviews, including one lunch interview.

    Generally, you will be asked primarily coding interview questions and potentially one or two system design questions as well.

    The more experience you have, the higher proportion of system design and topic-specific questions you can expect to be asked. Google rarely asks any system design questions to engineers with less than 5 years of experience.

    Each interviewer collects feedback on how well you performed during the one-on-one interview with you. This feedback is collected by each interviewer independently as to eliminate cross-chatter and biases between your interviewers. If you felt as if you performed subpar in one of the interviews, that baggage stays there and does not follow you into the next interview.

    Where And What I Used To Practice

    I used Leetcode throughout. I would advise you to buy a premium subscription since the company specific tracks, mock interviews are worth it. I started with Google tagged questions , and my initial target was ~100 where I solved a mix of 15% easy, 80% medium and rest hard. This was before I started applying. In total, I solved around ~300 problems on Leetcode.For onsite, I solved problems topic-wise picking up 45 from each topic , some from the Google track and gave mocks . Towards the end, I also participated in Weekly Leetcode contests, its quite helpful.

    Also, InterviewBitwas helpful while practicing topic-wise. I used it as a reference to make sure I did some problems from each bucket.What I observed after my prep was that, even though I focused on Google tagged problems, other companys interviews seemed easy/doable to me without any special prep.

    What Does A Data Scientist At Google Do

    At a high level, data scientists at Google evaluate and improve the companys products and services using statistical methods. In practice, this means bringing data analysis to every stage of the product development and deployment process, from the brainstorming phase to product creation and development, to identifying ways to improve on whats already been built.

    Regardless of the team they join or the projects they work on, data scientists at Google have a few things in common: most have backgrounds in computer science, economics, mathematics, statistics, or a related field know coding languages such as Python, SQL, or Java can deploy machine learning and artificial intelligence algorithms, and arent afraid of experimentation with different data structures and quantitative analysis methodologies.

    With these skills as prerequisites, Googles data scientists can specialize in different facets of data analysis depending on the team they join. For example, Artem Yankov, a Springboard mentor and Google data scientist on its forecasting team, helps Google determine how many customer service representatives should be hired globally to support its products and services both around the world and in different languages.

    In order to achieve the most accurate forecasts possible, Yankov spends the bulk of his time ensuring that the data pipeline reflects the most current understanding of the business because if the data is off, then the results will also be off.

    -As most of the questions are technical and it will be the obvious expectation that you know algorithms and their implementation.

    -They expect you to know the core CS subjects like Operating System, Computer Network, Distributed systems .

    -They expect you to ask questions. They will give you vague questions and that’s intentional.

    -You should always ask relevant questions to make it more clear without making assumptions on your own. Make the problem clear before directly going to solve it.

    -They expect you to think out loud. It will make them at ease as they can really hear how you are approaching the problem

    -They do not expect the perfect solution in first attempt. You should come to a working solution and iterate it, rather than taking much time and coming with perfect thing.

    The Google Phone Interview

    For the phone screen, you are interviewed by at least one Google employee who provides you with a coding question. You share a Google document with the interviewer and use it to write code for the question asked by the interviewer.

    Protip: Coding in Google Docs sucks, but if you update your preferences it can make your life 1000x better. Learn how to do that here.

    This interview will focus on your ability to produce code without an IDE . Typically, the question asked will be one that can be solved by a brute-force solution, and then progressively improved upon.

    The phone interview is about 30-45 minutes. Assuming you did well, the Google recruiter will reach back out to you to give you the next steps if they decide to move along with you.

    Dont be disappointed if they ask to do a second phone interview. Thats totally normal if they dont feel like they were able to adequately assess you the first time and doesn’t have any bearing on your later interviews.

    Statistics And Machine Learning Questions

    Google Onsite Interview Experience ( A Failed Attempt !!!) | Sprint Master

    Googles data scientists have to derive useful insights from large, and potentially complex, datasets. Thus its imperative to have a strong understanding of statistics. Out of all the question categories, general statistics and statistical probability come up the most often in all stages of the interview process. Take extra time to study this section.

    Review fundamental statistics and how to give concise explanations of statistical terms, with an emphasis on probability. Some general topics that have come up before include p-values, MLE, confidence intervals, and Bayes theorem. In addition to these general topics, youll find complete questions to work through below.

    Your interviewer will also ask questions specific to machine learning, as Google data scientists must build algorithms that improve and remain accurate over time. General topics that have come up before include regression models, feature selection, and recurrent neural networks.

    Let’s get to the example questions.

    Google data scientist interview questions – Statistics and machine learning

    General Statistics

    • In what situation would you consider mean over median?
    • For sample size n, the margin of error is 3. How many more samples do we need to make the margin of error 0.3?
    • What is the assumption of error in linear regression?
    • Given data from two product campaigns, how could you do an A/B test if we see a 3% increase for one product?

    Tip : Implicitly Show Your Googleyness

    To prepare your stories, compare your past experiences with Google traits, along with personal values youre most proud of, and select the stories best reflecting those traits and values. You want to show that your values and experiences perfectly match what recruiters look for.

    So what are these famous Google traits? Above all, Google places emphasis on kindness, empathy, and humility in their people. Successful candidates also excel in these criteria: learning ability, teamwork, communication skills, leadership.

    • Learning ability: Google not only values excellent cognitive abilities, but also problem-solving ability, curiosity, and ability to learn.
    • Teamwork: Working at Google demands that youre a great team player. Merely being an independent, hard-working employee isnt going to cut it youve got to work, think, and succeed in teams.
    • Communication skills: succeeding in teams also requires excellent communication skills, and this holds true not only for Google but many companies.
    • Leadership: Google defines leadership as the willingness to step into a difficult problem and step out when their expertise is not needed. One person is not always going to be the right leader for everything Google does work will be handled in small-sized teams consisting of people with different skill sets.

    Who Do You Believe Are Googles Main Competitors How Does Google Stand Apart

    With this question, the hiring manager can determine whether you have a solid idea of which other companies dominate spaces where Google also sits. This can be especially relevant in product-oriented roles, including everything from product manager positions to software developer jobs, where finding opportunities to outshine other companies comes with the territory.


    Google has several main competitors, including Microsoft, Facebook, Netflix, Waze, and several others, depending on the specific space. One of the main differentiators is Googles ability to integrate its services, creating a cohesive cross-platform experience. Additionally, Google has such a wide range of offerings. It promotes a degree of familiarity you dont necessarily get with some of the competitors, making using the products and platforms feel like a natural part of daily life.
