    Started with HR screening, and followed by a phone interview with a team member from R&D department. They are very nice and explained the questions very patiently. The phone interview with the team was a behavior-and-technical interview. They asked questions based on your resume and experiences.

    Technical in terms of analysis but emphasis on client communication. most of the time the more advanced stuff is left for later in the process. either way it came off as impressive. other than that, this was a normal interview with a friendly hiring manager. this was for a consultant

    Entretien de Data Scientist

    Aucune offre d'embauche
    Expérience neutre
    Difficulté moyenne

    Candidature

    J'ai postulé en ligne. Le processus a pris 3 semaines. J'ai passé un entretien à Precima (Chicago, IL (États-Unis)) en février 2017.

    Entretien

    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.

    Questions d'entretien d'embauche

    • Assumptions of linear regression, survival analysis.
      What is VIF and how to calculate it?
      Basic clustering question.
      linear programming.

    Le processus a pris +3 semaines. J'ai passé un entretien à Precima.

    Entretien

    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.
