BCG Data Scientist Interview Experience: repeated technical and business cases

After an HR screen, I completed an online coding and assessment stage before a series of technical rounds with live case work. The pattern kept returning to coding checks and data-science cases rather than general consulting questions alone.

The final stretch combined multiple technical cases with PEI and MBB-style business-case thinking applied to data science. Each interviewer appeared to test a slightly different angle, and the accumulating workload made a stumble hard to recover from. The later rounds became more difficult and stressful. I did not get an offer. It felt less like one decisive performance than proving endurance and technical range across many demanding rounds.

Location: Hong Kong. Overall feedback: negative. Offer status: no offer.
