Expedia Group Senior Manager Marketing Analytics interview questions

Intial phone call with recruiter followed by take home assignment on A/B tests, forecasting and an optimization problem. Phone interview with hiring manager-basic questions like tell me abt yourself, why expedia, duscuss some projects. Onsite interviews with 6 ppl. I feel 5 out of 6 were very good, 1 was not so good. Also had 2 video interview with the London team. Questions ranged from past projects to behavioral to some vague problem solving. A lot of question around AB tests. The Data Scientist asked a lot about hypothesis testing, logistic regression, decision trees. T tests, F tests. No programming questions. I was really hopeful but got a reject after 3 long weeks.
