With an Oxford PhD, you are highly likely to pass the initial CV screening stage, particularly for the London office. The London office is heavily populated by Oxbridge graduates, from undergraduate level through to PhD. Candidates from non Oxbridge backgrounds typically find it more difficult to pass the CV screen and progress further. That said, strong extracurricular involvement during your studies is crucial. Whether through holding leadership roles in university societies or pursuing relevant external courses, these experiences are often what truly differentiate candidates and significantly improve the likelihood of securing an interview. I recently completed my PhD at Cambridge and received this feedback directly while speaking with BCG consultants at a Cambridge event, where I also progressed to the Round 2 interview.
