    Application

    I applied online – interviewed at Google.

    Interview

    First, a very helpful recruiter contacted me and asked a few questions about my experience. After a few days, she said I could proceed to the second stage: a technical phone interview.
    I was interviewed by a random engineer from a random department. He asked about my background, and let me solve a probability problem. The question itself was not too hard, but I didn't do it very well (because I hadn't used it for many years).

    Interview

    Hiring process was very smooth, took less than 2 weeks to go through 5 interviews: 1 phone call and 4 on site interviews. Got feedback the same day after all interviews and the offer in less than 2 weeks since the initial interview. Recruiter and interviews were very professional and the interviews were not particularly hard, not the the famous "how many golf balls fit in a bus" type of questions.

    I applied online. The process took 2 weeksinterviewed at Google in February 2011.

    Interview

    Two phone interviews, one long in person interview with 3 people, one remote video. They reached out to me directly after I submitted an interesting answer to an online interest survey sent to campus by their outreach team. The phone interviews were scheduled soon after followed by the in person interview. The first two were easy but the last one with remote video was trickier due to some video lag and lack of eye contact to connect with interviewee.

    I applied online. The process took 4 weeksinterviewed at Google (Mountain View, CA) in October 2014.

    Interview

    So when I saw the Ad online, I just applied and was not sure they would even respond since I know Google receives a lot of applications per day and I always assumed they had a bias for Ivy League schools. But Alas, 2 weeks later I received a call from a recruiter and she asked me a few questions but it did not take her long during that interview before she told me that she was putting me to the next round.

    For the next phone call round, I talked to one of the guys in the team and he asked me a whole bunch of statistical questions and I was able to answer them all correctly. Got a call from the recruiter saying I made it to the round with the Hiring manager, again I had done my homework so I was able to quickly answer her questions and some were really hard statistical questions so I suggest you read the text book to familiarize yourself with statistical because they will ask you the 5 assumptions of logistic regression vs ols. Nailed it and moved on the final in person interview.

    At the onsite interview I was interviewed by 5 people but within minutes I knew I did not stand a chance and I will explain why at the bottom. But firstly the 1st interviewer was nice , answered all questions quickly and correctly. The next interviewer was very cold, never smiled and had a background in PhD in statistics. Asked me a bunch of questions , answered them correctly and then he started asking me very hard mathematics questions which he started calculating on the white board, I didn't get one correctly and at the end of the interview I had to ask him why he was asking such hardcore mathematics questions when the job specifically indicated that it only needed minimal stats background. He said sorry, i just went on a tandem (but since i had missed one of his very hard questions I felt that was not fair). Next came a guy who was more interested in telling me how awesome he was , which country I came from and about his girlfriend (very unprofessional). But talking to this guy I could already see some hints of biases as he asked me which school I had gone to and to name some world renown professors in the department , when he had already told me he did not know my school, which by the way is one of the best public schools , top 10. Then he went on to talk about his professors at the Ivy league he went to etc. Quite unprofessional. The last interviewer was the hiring manager and she too asked very difficult statistical questions but I was able to answer them quickly , they require you to think on your toes. After I finished these interviews I knew I had done extremely well because these were statistical questions and I had answered almost all of them correctly except the hardcore mathematics equation question which had no reason to be in the interview. But as soon as I left I knew that the team would not hire me and he is why?

    How do you stand a chance to be recruited when 4 of the interviewers are males and all 5 interviewers are white and they all have Ivy League backgrounds and although I go to a top 10 public school but still it's not Ivy League. The other 2 guys who made it to the top 3 onsite interviews were also white males from Ivy Leagues. I am sure that interviewer did not tell that he didn't know his school or to name a renown professor in their department. Google needs to change something seriously. I am not saying I didn't stand a chance because of my race or gender but you can tell by the types of questions you get that these interviewers are already biased towards ivy league e.g. One interviewer asking me to name some world renown professors in my department (did not understand the relevance of that to the interview) and then telling me, I don't like D.C (promixty of where the school is) and then proceeding to tell me that they thought my school was rural. Social Science studies predict that most people hire people who look like themselves and somewhat similar backgrounds to them. My recruiter told me that I did very well in the interviews and she herself could not understand why I was not picked but I will leave that to Google. All I am saying is that they should train their interviewers to have less bias towards none ivy league candidates because if you check on linkedin about 90% are ivy league. I got accepted to an Ivy League but could not accept the place because my parents are poor , so the fact that I went to a public school doesn't mean I am not as smart as someone who didn't attend an Ivy League school.

    I applied online. The process took 4+ weeksinterviewed at Google (Mountain View, CA) in September 2014.

    Interview

    Applied online and got contacted by a technical recruiter. I had to fill about 13 questions first - i guess this was a kind of screening process. and she got back to me 2 weeks later saying that I will have a phone interview. In the phone interview, I answered questions but with the interviewer's hints. The recruiter got back to me a week later saying that she's not moving forward with me as they are looking for candidates with stronger problem solving skills.

    Interview

    On-site interview at their London office. Had 3 interviews in total, 2 of them were video conferences. Each was 45 minutes. Everyone was very nice. They tried to gauge how much you know and if you don't know a particular area, they'll ask something easier. So it's hard to say how much I could have done more to land the job.

    I applied through an employee referral. The process took 4+ weeksinterviewed at Google (Mountain View, CA) in January 2014.

    Interview

    Internal referred followed by two round of phone interviews. Both interviews focuses on technical questions. The first interview has lots of questions on the fundamental statistics models, such as regression models, experimental design. The questions are like typical exam problems, but requires quick instant responses. The second interview also fucused on statistical questions, but were asked in a practical context. The interviewer described several projects with me, and for each project he asked questions about how you would like to plan the project, what models would you use, what were the alternative choice you have, reasons you picked that model, etc.

    Interview Questions

    • If you will propose a project in the quantitative marketing team, what will you propose and how will you plan the project?   1 Answer

    Negotiation

    Google offers a generous stipend for interns and I don't think there is any need to negotiate.

    Interview

    I applied through an employee referral. Two recruiting managers contacted me after 10 days and I had two phone interviews.

    Interview Questions

    • The first interviewer was very unfriendly and the second interviewer was friendly. Due to my statistics background, they both asked some statistical questions including design of experiments for an effective advertising campaign, comparison of two survey results, coding questions and how to handle multicollinearity in predictors and large dimensional data, etc.   Answer Question
