Meta RDS Stats Questions

I'm interviewing for this role in 2 weeks and I'm wondering about the depth of the stats questions.
For example in Hypothesis Testing are you required to come up with formulas for tests (besides t-Test and Binomial Test maybe...) or MLE estimators for certain models or are they just asking in which scenario you would apply which test, which model etc.?
