Candidates describe BCG Gamma analyst interviews as case-heavy, with technical checks layered on top. Two of the four reports describe an opening online test: one called it a tough, IQ-style assessment that needs careful time management, and another described an automated screen with a chatbot. One candidate also mentions a math and reasoning round, so timed quantitative practice is worth your time.
Cases are the most common theme. Candidates report market sizing and profitability problems, such as estimating how many kids play sports or the economics of a hospital chain. One candidate had back-to-back cases in a single day, and another says interviewers pushed hard for depth in their reasoning. Structure your answers and explain each assumption.
Technical questions look lighter than the cases. One candidate was asked about SQL and Excel, including how VLOOKUP works. Another reports easy-to-intermediate questions touching on types of machine learning. A third, applying for a Data Analyst role, got a take-home with a dataset of millions of rows, to be processed in Python and presented in Tableau. That candidate then walked a senior data analyst through the findings in a conversational interview, partly in Spanish.
Fit questions came up as well, mainly why you want to join BCG, plus your background and a weakness. Outcomes were mixed: three candidates reported no offer and one reported an offer. The reports cover different analyst tracks, including a summer role, so check your own recruiter's schedule.

Synthesized from candidate reports. Individual experiences may vary.
Candidates report an opening online screen. One describes a challenging IQ-style test with multiple-choice and short-answer questions, another a math and reasoning round, and another an automated chatbot assessment. Timed practice is a sensible way to prepare, though formats may differ by role and year.
One Data Analyst candidate had a roughly ten-minute Zoom call with HR covering why they applied and logistics such as citizenship. Another candidate mentions an HR conversation among their rounds. Expect to explain your motivation for joining BCG.
One Data Analyst candidate was sent a case-style project to finish in three to five days. It involved millions of rows, processed in Python and presented in Tableau. This was a single report, so confirm with your recruiter whether your track includes a take-home.
Several candidates report case interviews, some over Zoom and some in person. Topics included market sizing and hospital-chain profitability. One candidate describes two case stages with two cases each. Interviewers may probe your reasoning in depth, so practice structuring and stating your assumptions out loud.
Technical questions reported include SQL, Excel (such as VLOOKUP) and basic machine learning concepts. The take-home candidate presented their findings to a senior data analyst. Another candidate reports meeting a Team Lead, Director and Senior Director. Timing and sequence are not consistent across reports, so treat these as possibilities.
