Every tip below is grounded in the oc&c process and linked to authoritative sources so you know exactly what to practice.
What is oc&c and why does the interview matter
oc&c is a strategy consulting firm known for treating each client problem as unique and emphasizing “uncommon sense™” rather than cookie‑cutter frameworks. The interview matters because oc&c’s recruitment process deliberately tests for the firm’s core behaviors — structured thinking, numerical rigor, business judgment, clear communication, and cultural fit — not just memorized frameworks oc&c Careers oc&c About.
Candidates typically face a two‑round process: each round contains two 45‑minute case interviews plus behavioral discussion, and there’s also a 45‑minute GMAT‑style online test earlier in the process Career in Consulting CaseBasix. Understanding why oc&c hires the people it does helps you prioritize what to practice.
What five core skills does oc&c test
oc&c evaluates a compact set of capabilities that surface across the case, PEI (personal experience interview), and online test:
Structured thinking: breaking ambiguity into logical components and sequencing analyses clearly. This is the baseline skill oc&c expects CaseBasix.
Analytical ability and numerical literacy: fast, accurate calculations and reading data under time pressure, including no‑calculator sections in the online assessment Management Consulted Career in Consulting.
Business judgment: prioritizing the most impactful issues and converting analysis into practical recommendations — oc&c prefers original, client-tailored thinking over off‑the‑shelf frameworks oc&c Industries.
Communication: explaining your approach and findings clearly in a fast‑moving discussion; oc&c emphasizes clarity over rhetorical flourish CaseBasix.
Cultural fit: demonstrating curiosity, humility, and the “uncommon sense” mindset — you must show you treat problems as unique, not as a slot for a known template oc&c About.
When you prepare for oc&c, make every practice scenario test one or more of these skills rather than chasing generic frameworks.
How does the oc&c two round interview structure work
oc&c normally runs two interview rounds. Each round contains two 45‑minute case interviews with behavioral questions folded into the discussion. The interviews are designed to mimic real client conversations: fast, interviewer‑led, and focused on clarity and impact Career in Consulting CaseBasix.
Key structural points to remember for oc&c rounds:
Expect the interviewer to drive the flow. Ask clarifying questions but be ready to respond to specific prompts and pivot quickly. This is an interviewer‑led format rather than candidate‑driven structuring CaseBasix.
Behavioral questions (PEI) are not a separate, long segment every time — they’re woven in, but you should budget ~20–40 minutes total for your PEI content across interviews Career in Consulting.
Interviewers are looking for crisp, evidence‑based conclusions and a clear line from analysis to recommendation. Practice communicating a takeaway within the first minute after an analysis block.
Understanding the structure lets you manage time and expectations during each 45‑minute slot.
How can I master the oc&c case interview under pressure
Mastering oc&c cases is about demonstrating clarity of logic, quick numerical handling, and pragmatic recommendations. Follow this step‑by‑step approach tailored to oc&c:
Listen and clarify quickly: In interviewer‑led cases, ask 2–3 targeted clarifying questions to remove ambiguity. Keep them fast and purposeful CaseBasix.
State your game plan: Give a one‑sentence roadmap that prioritizes the most critical lines of analysis (don’t recite a framework). oc&c values prioritization and business judgment.
Break the problem into logical buckets: Use MECE thinking but avoid forcing a classic framework. Show how each bucket links to profitability, growth, or operational impact.
Do focused math: Practice doing no‑calculator arithmetic cleanly. Use rounding only when justified and state assumptions clearly Management Consulted.
Synthesize at each checkpoint: After a calculation or interpretation, state the implication for the client and what you’d do next.
Close with a concise recommendation: End with 3–4 actionable points, risks, and quick next steps tailored to the client’s context.
Practice interviewer‑led cases specifically — it’s a different rhythm from candidate‑driven cases and matches oc&c’s interview style.
