  • Shortest Distance in an Unweighted Adjacency-Matrix GraphMedium

    This problem tests implementing breadth-first search (BFS) on an unweighted, undirected graph represented as an adjacency matrix to find the shortest path distance between two vertices.

  • An Unweighted Graph Turned WeightedBCG · Forward Deploy Engineer · Senior+ · Technical Screen · Aug 2026
    Rejected

    A friend referred me for a Senior Forward Deploy Engineer role. The interviewer was very nice. The first 30 minutes were a deep dive into my projects, with many questions related to AI. The last 30 minutes were a live coding problem: find the shortest path in an unweighted graph represented by an adjacency matrix. Given the adjacency matrix of a connected, undirected graph with no loops or multip…

  • BCG Consultant Interview Experience: Switching from fit to interviewee-led casesBCG · Consultant · Online Assessment · Jul 2026

    After recruiter outreach, I went through a bridge stage that led to a final-round invitation. The final stretch included an online technical assessment and case interviews: first one case, then two cases back to back. Behavioral questions filled the first half, while the case discussion took over in the second. The process was more demanding than it looked. I had to switch quickly from fit questi…

  • BCG Data Scientist Interview Experience: repeated technical and business casesBCG · Data Scientist · HR Screen · Jul 2026

    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…
