I applied through an employee referral. The process took 4 weeks. I interviewed at Boston Consulting Group
Interview
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.

Coding challenge, then soft skills which i did not get to. Coding challenge was online timed in a third party tool. Not very hard but needed more time and didnt move quick enough.
The process includes six stages: HR screening, CodeSignal online assessment, basic pandas and data science case interview, followed by three business case interviews focused on practical problem-solving and business impact.
