OC&C Interview Rounds 2027: From Online Test to Partner Interview
The OC&C interview rounds for the 2027 intake run from CV screening through an online test, a one-way video assessment, two rounds of case interviews, and a final partner round. Miss what any single stage tests and you prepare for the wrong thing. Here is the full map so nothing catches you off guard.
The occ interview rounds in Order
Round zero is the application: CV plus a mandatory cover letter, screened by humans at a boutique where every application gets read. Next comes the online test — timed numerical and logical reasoning that cuts the pile fast. Clear it and you face the one-way video assessment: pre-recorded answers, one take each, testing communication and commercial instinct. Then the case rounds begin: first-round interviews with consultants (typically a case plus fit questions), second-round interviews that go deeper, and finally the partner round — a longer, harder case with a partner who probes your thinking relentlessly.
What Each occ interview rounds Stage Tests
The occ interview rounds filter different skills at each gate. The online test screens raw numerical speed. The video assessment screens communication under pressure. First-round cases test structured thinking and mental math on commercial problems. Second-round cases raise the bar on commercial judgment — can you think like an investor, not just solve a puzzle? The partner round tests everything at once, plus presence: partners want to see someone they would put in front of a client tomorrow.
How to Prepare for the occ interview rounds
Do not prepare generically. For the online test, drill timed numerical reasoning. For the video assessment, record yourself daily on the real questions. For case rounds, practice CDD-style cases and market sizing out loud with a timer — and do every calculation without a calculator. For the partner round, practice defending your recommendations under pushback, because partners will challenge your assumptions to see if your thinking holds. Map your prep to the calendar: test first, video second, cases third.

occ interview rounds: the Weakest Link
The brutal truth about the occ interview rounds: they are sequential, and each is a hard cut. A perfect case performance means nothing if you failed the online test three weeks earlier; brilliant fit answers cannot save a collapsed partner case. Candidates who "focus on cases first" and wing the early screens get eliminated before their strengths ever matter. The 2027 intake is already moving on rolling review — prepare every round in order, or do not be surprised when the chain breaks at its weakest link.
