WTW Data Scientist Graduate interview questions

There were three stages: an initial online application, followed by a Hirevue recorded interview and gamified assessment. The final stage was invitiation to a virtual assessment centre. The virtual assessment centre was split into three parts; a 'networking' session where we got to meet and ask current grads questions, a competency interview [1 hour] and a technical interview [about 45-50 min]. The competency interview was very lengthy and although questions weren't difficult, felt unnecessarily tedious with the amount of questions asked. Technical interview was split into three parts; first had to answer questions about a dataset, then a probability maths question. For the final part was shown many graphs of performance of ML models and was asked to interpret/explain each one.
