    Data Scientist Interview

    Positive Experience
    Average Interview

    Application

    The process took 3+ weeks. I interviewed at Precima.

    Interview

    An HR contacted me regarding a Data Scientist opening at Precima. He scheduled a phone interview with me which was just basic screening. I was then contacted for another round of phone interview with their Data Science team leader. This interview consisted of a mix of technical and logical questions. The questions were very straight forward and I think I did well but a week later I got a reject from this. When I asked for feedback it looked like they were more aligned to hire a PhD. candidate.

    Data Scientist Interview

    Anonymous Interview Candidate in Chicago, IL (US)
    No Offer
    Neutral Experience
    Average Interview

    Application

    I applied online. The process took 3 weeks. I interviewed at Precima (Chicago, IL (US)) in February 2017.

    Interview

    Applied online and about two weeks later got a call from HR, basic questions about my background. Then scheduled a one hour long phone interview with one of their data scientist.
     They are either doing super advance machine learning or they do not know machine learning at all. When I say super advance, I mean they are going to create their own machine learning algorithms, which I highly doubt based on the questions he asked, very basic statistics questions, like linear regression, model assumption, collinearity etc.
    It feels like the interviewer is from mechanical engineering background, if you want to pass the interview, refresh your statistics knowledge with a book like "statistics for mechanical engineering", the statistical questions he asked are very typical mechanical engineering statistics, like linear regression, survival analysis(which is called reliability analysis in mechanical engineering area), simulation. From the conversation, I call tell the SAS procedures they use a lot are pro reg, proc glm, proc logistics, proc fastclus, proc lifetest and proc phreg.

    Interview Questions

    • Assumptions of linear regression, survival analysis.
      What is VIF and how to calculate it?
      Basic clustering question.
      linear programming.
      optimization
      3 brain teaser questions:
      1. burn two ropes.
      2. bacteria double it self every minute, 100 minutes to fill a cup for one bacteria, how long does it take for two bacteria
      3. 10 machines produce coins, one of them is broken. how to use one scale to find out which with only one measure.   Answer Question
