Hi everyone,
I have Microsoft onsite rounds scheduled for this Friday, and the recruiter mentioned focusing on the following areas for the first two rounds:

R1 (seems like LLD):

• Logical implementation and problem-solving related to AI (e.g., caching to reduce AI costs)
• Observability for LLMs

R2 (seems like HLD):

• Designing an AI application
• Evaluating the design

I’ve been working on AI agents for the past year, but I don’t have deep expertise in core AI/ML concepts. I’m also a bit confused about whether I should focus more on AI/ML and LLM concepts or stick to standard HLD and LLD preparation.

Since I’m short on time, I’d really appreciate any advice, resources, or preparation tips from the community.

Thanks in advance!
