I don't think these question has owt to do with seniorship. An interviewer can ofc pick a few of them to understand a programmer's familiarity with the ecosystem, but usually another approach is used for senior/staff roles—system design interviews and behavioural questions. Seniorship is not about technologies. On the contrary, it's about being technology-independent. It's also about your maturity in problem-solving and high-level design and planning, your mentorship skills and reliability for the business, and so on.
