Microsoft Research Intern interview questions

the interview process was extremely easy, we talked a little about myself and my goals and the rest of the time we spent it talking about my projects. therefore, I would recommend studding your projects extremely well so you can about them in depth and answer any questions if they have any.

The interviewer asked several papers related to LLMs but assume interviewees know all of them. But in fact, I think it is difficult to know all of them in advance right?
