How KPMG interviews Data Scientists
KPMG is a Big Four firm and major recruiter across audit, tax, advisory and technology. Its Launch Pad process aims for fast decisions, assessing values, aptitude and commercial awareness, with qualification funding on most graduate routes.
For a Data Scientist specifically, KPMG pairs its standard assessment with a technical bar focused on statistics & probability, sql, python. Data science interviews test whether you can turn ambiguous business problems into measurable analyses. Strong candidates pair technical depth (stats, ML, SQL) with clear communication and product judgement.
