Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Given a customer brief and a sample slide deck a few days in advance, run a 20-30 minute mock meeting with a "customer": present the material comfortably and answer the customer's questions. Asked in the late onsite round stage. Tests product knowledge and presentation/soft skills; the AE usually leads meetings but the SE must keep the customer informed about next steps. Reported follow-ups: Answer the customer's questions on the presented material.
