I applied online. The process took 3 months. I interviewed at Boston Consulting Group in Nov 2025
Interview
Lengthy, there were numerous screenings before making it to the technical interview, which seems to be the primary barrier. They expect you to prepare for their specific interview format way too much to acquire top data scientists who do not spend their time on case interviews.
Interview questions [1]
Question 1
Mainly just a technical case, which is just a business problem that you need to work through utilizing data science. Mine was a demand forecasting problem, so nothing very exciting. They claim to want talent at the forefront of the field of data science, but simultaneously interview for bleh business data science knowledge, no GenAI, no deep learning. Not sure why they passed me through the screenings seeing all of my internship experience as a new grad was technical GenAI and deep learning internships at research institutions.
I interviewed at Boston Consulting Group (Boston, MA)
Interview
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.
