Applied Online. Then got Virtual video interview. Guessing the next stages are phone interview and onsite with interviews being case-based and how to understand how to use data science techniques in the case.

    Entretien

    This was for a GAMMA Consultant position, which is for BCG's data science arm. Went through three rounds before getting cut:

    1) Recruiter phone screen, which was very casual and low-key, mostly explaining background, fit, and a project on my resume.

    2) Technical assessment, which was administered through HackerRank, composed of a series of programming exercises to pre-process data and train a model, as well as two ML / time series theoretical questions at the end.

    3) Technical case interview via interview, with a GAMMA Data Scientist. The case can vary depending on the interviewer from what I heard.

    Ultimately, I needed a lot of clarification in the case and was too slow on developing analytical solutions. GAMMA is looking for the best of best of quantitative minds as they are competing with QuantumBlack. Those skilled enough to get through the technical case move on to a business case, and then from there go on-site to either Boston or LA to do multiple rounds of additional technical/general case interviews. A very intensive process overall.

    Entretien

    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.

    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.

    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.

    J'ai postulé via un recruteur. Le processus a pris +3 mois. J'ai passé un entretien à Boston Consulting Group en mars 2018.

    Entretien

    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.

    Entretien

    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!

    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.

    The first round was a hackrank test where my coding skills were put to test. Once you get past that, the interview contained series of cases containing both Data Science and traditional strategy. I had a total of 6 cases (3 DS and 3 strategy cases).

    The overall process was quite seamless. The HR was very helpful, especially with feedback and preparation for next rounds. The cases were quite interesting and challenging which made the interview exciting.
