Quantitative Analyst Interview

Easy Interview

Application

I applied online. The process took 1 day. I interviewed at Google in July 2019.

Interview

Application
I was reached out directly by another Quantitative Analyst for tech screen. He was very late when he called me and told me since we are late, lets begin and started asking questions directly. Questions were easy but he would complicate it by asking weird questions around it.

He didn't introduce himself nor asked about my background and I had to ask those things myself when he said do you have any questions? I can't believe this is how Google conducts interviews without any recruiter and some guy reaching out directly who is not punctual and doesn't have any etiquette to introduce himself or tell about team and role. (Foreign accent), It's been weeks since I interviewed and there is no feedback or update as I expected.

Also, you cannot expect someone to solve math problem verbally when formula is complicated and involves square root calculation

    I applied online. The process took 5 weeks. I interviewed at Google in July 2019.

    Interview

    Applied online in late May as a recent PhD graduate. E-mailed by a recruiter within a week, who scheduled a phone call with her for mid-June and had me fill out a questionnaire describing my data analysis experiences and statistical skills. The phone call was 5 minutes where she told me the next step would be a technical Hangouts interview with a Data Scientist and to study applied statistics and programming in a Google Doc. My interview was scheduled for early July. In the Hangouts interview, he asked just stats questions, no programming. I was unable to solve the last problem, he didn't really provide any hints. The next day the recruiter told me I would not be moving on.

    Difficult Interview

    Application

    I applied through an employee referral. The process took 6 weeks. I interviewed at Google (Mountain View, CA) in January 2018.

    Interview

    The questions in round 1 ans 2 was pretty good. Round 3 and 4 were more open-ended. I did okay in round 3 and 4. But the passage between round 2 and 3 was pretty bad. My lunch interviewer was 30 mins late and we had to eat in 10 mins and run a 35 min walking distance in 15-20 minutes and still reach the other interviews ofice late for my round 3 and round 4. Shocking was that this was not informed to the other interviewers.

    Anyway, the interviewers were nice. But I had a horrible experience with the hr, who called a week later an congratulated me for having my application move forward with lots of good praise from the interviewers and asked for my latest cv to move forward to team match. Then in two days suddenly a holistic review round popped up and in the next day I was rejected. This has been such a humiliating situation since I did quite a bit of research with the team matching process and was pretty proud to tell my family and a couple of close friends. They should not play with such big news in a childish fashion like this
