I attended a school career fair and got contact information of an employee. So I asked him if he can refer me and he did. I got the first interview and it was an experience interview.

    Vorstellungsgespräch

    initial phone interview, followed by an 8 hour task to analyze a data set and report findings during the next webex interview.

    The problem is that BCG does not respect your time during this process. First, the dataset provided had no 'solution'. They asked me to predict an outcome when the training data showed in every way that it was a randomly selected subset. Second, after providing a technical explanation of the work I did on the data set I was informed that they were simply testing me on presentation skills. I found that the interviewer is likely not interested in critical thinking or problem solving talent. Further, the interviewer refused to provide me with any insight into the data set I was tested with. That shows little respect for my time.
    In short, don't waste your time unless you really want to work with these guys. I don't. I'll stick with real Science!

    Vorstellungsgespräch

    Screen with recruiter. Massive take home technical case, followed by a video interview where I presented on the case (the interviewer was not especially familiar with the case). Was told I'd be proceeding. That was followed by a frantic attempt by BCG to schedule more interviews for me (including an in-person). I gave them availability, and then they stopped replying to my emails. A couple of weeks later I got a form rejection. That stung a bit--the take home case was about 8 hours of work, and to not get thanked for my time after they selected another candidate (I presume, given the job posting is gone).

    The case is basically a Kaggle problem, except you're supposed to make a presentation for a mock client. The case is kind of silly -- it's a churn problem with standard modeling issues -- categorical data, missing values, noise, a poorly defined objective, a poor data dictionary, etc. The data appeared artificial, and modeled decently but only with non-linear techniques--it looked like they had created the data that way (there was a massive gap between performance of linear and non-linear models, far above what you would see in a real dataset). They also set some traps in the questions they asked you, where you really need to think about what's useful to the client rather than answering an academic problem.

    Bewerbung

    Ich habe mich über einen Personalvermittler beworben. Der Vorgang dauerte mehr als 3 Monate. Vorstellungsgespräch absolviert im März 2018 bei Boston Consulting Group.

    Vorstellungsgespräch

    I interviewed for a data scientist role at the Gamma Group. There were many individual interviews with recruiters, data scientists, a presentation, case studies, etc that spanned about 3 months.

    On the whole, I could certainly understand why they would want to be thorough in their screening, but it's a lot of work on the interviewer and they made little to no accommodations for my schedule. In almost every interview, they would ask for my availability and then email me back later saying they needed to me interview at some other time that was difficult for me.

    The data science project was straightforward but time consuming. They asked a lot of reasonable questions and wanted to see if you could present the topic to someone who was not necessarily technical.

    For the most part, the interviews were straightforward and everyone was nice. The last person I talked to made a lot of strange faces during the video call and seemed to be in a bad mood and had some odd things to say about my personal life, which I thought was rude. This was the case study, but the format was very different from what was presented for practice online and he seemed to have no interest in going through the motions of it.

    Overall, the process is long and most of the work makes sense, but they have little regard for their applicants. One unfortunate interview situation can invalidate the previous six over three months, and that's a lot of your time gone.

    The interviewer asked a lot of technical questions for the data science project, which is clearly well designed to include many possible issues in real data set. Need a lot of hands on experience to perform well.

    Took 2 months to get back after application. Sent a data science challenge on hackerrank.
    Given a dataset which we cannot even see properly on hackerrank, build 2 ML models and answer insight related questions within 2 hours. It made no sense. The dataset was in raw form (transaction level data), had to be studied and converted into features and target, split for training/testing and report accuracy. This is not how a data science task can be completed.

    They messed up stress interview with the technical interview. I was asked to spend several days to finish an analytics case (a very simple case similar those in Kaggle) before the case interview. A junior interviewer from the BCG Gamma in Boston interviewed me. He was obsessed to play a tough 'CTO' of the client, although his understanding of Data Science stopped updating about 3 years ago. Sometime, he just didn't listen. When he realized his arguments were invalid, he was angry. In the end, I felt like that they were probably used the 'case interview' to collect some analytics notebooks for their daily works.

    Vorstellungsgespräch

    I applied online for a Data Scientist position with BCG GAMMA.

    Initial phone interview with Recruiter, followed by 3 rounds of interview.

    1st round - I was given data for a homework case a week in advance, and had to present the findings to a Principal.

    2nd round - 2 interviews. One with a Project Leader, and other with a Principal.

    3rd round - 2 interviews. One with a Principal, and other with a Senior Partner.

    All interviews were for 45 minutes. Around 10 minutes of behavioural questions, 25 minutes for a case, rest to ask questions.

    The whole process took 4 months.

    Bewerbung

    Ich habe mich über einen Personalvermittler beworben. Der Vorgang dauerte mehr als 2 Monate. Vorstellungsgespräch absolviert im November 2018 bei Boston Consulting Group (Toronto, ON (Kanada)).

    Vorstellungsgespräch

    So I was contacted by BCG and asked to apply for a Data Scientist role at BCG Gamma in their Toronto office. After the phone screening, I was asked to prepare for a case study interview. The HR was professional in communicating and providing me with the necessary information.
    The case study was a 30 minutes video conference, with one of the senior consultants (a different team - more business oriented). The case study was quite simple. I needed to calculate the return of an investment, based on two scenarios, and provide some analysis on what are the non-economical pros and cos of each approach. I did the calculations, and provided right answers to both cases, and chose one which was more advantageous.
    The interviewer, however, was extremely unprofessional. He was 6 minutes late (it was 30 minutes in total), and he had some food in his mouth when he was talking to me! Imagine you have prepared for this for a few days, and this is the first impression they give you.
    By the way, I did greatly in the interview, with no major flaws in my analysis, as the interviewer this not question any of my approaches, and the problem was quite easy. But, the funny part is that I got rejected after 2 weeks with a template email! They provided no information about the reasons I got rejected. I sent several emails and insisted for information. HR called me, but they had no information in my file either! The only reason I can think of is that the interviewer was not in a good mood that day!!! Very unprofessional and insulting experience.
