    Ich habe mich über eine Hochschule oder Universität beworben. Vorstellungsgespräch absolviert bei Precima.

    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

    Bewerbung

    Ich habe mich online beworben. Der Vorgang dauerte 3 Wochen. Vorstellungsgespräch absolviert im Februar 2017 bei Precima (Chicago, IL (Vereinigte Staaten von Amerika)).

    Vorstellungsgespräch

    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.

    Fragen im Vorstellungsgespräch

    • 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.   Frage beantworten

    Vorstellungsgespräch

    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.

    Schweres Gespräch

    Bewerbung

    Ich habe mich über einen Personalvermittler beworben. Der Vorgang dauerte 2 Wochen. Vorstellungsgespräch absolviert im April 2013 bei Precima (Chicago, IL (Vereinigte Staaten von Amerika)).

    Vorstellungsgespräch

    I had two phone interviews, one with TA and another with a member of the team I was to join, followed by an 1.5 hour in-person interview. I was contacted within 1 business week about next steps.

    The overall interview was not overly rigorous, but the types of questions tend to be on the difficult side. Depending on the role a candidate is interviewing for the questions can be very technical or require the interviewee to walk though how they would approach a specific business problem.

    Additionally, particular departments have different "knowledge tests" they give to candidates, depending on the role.

    Fragen im Vorstellungsgespräch

    • What is your ideal working environment?   Frage beantworten
    • What do you know about the world of "Big Data"?   Frage beantworten
    • How would you solve for pricing and promotion in a retail or B2B setting with big data? What distinguishes the two approaches from each other? What do they have in common?   Frage beantworten
