Microsoft Software Engineer interview coming up in two weeks. Please help!

I have an interview lined up with Microsoft for a Software Engineer role on the Azure Storage Test team. I haven’t interviewed in a while, and Microsoft is the first company to reach out. What should I focus on, given I only have 2 weeks left? Please help me out!

Is system design part of the interview process? Also, what rounds can I expect if I clear the OA? The recruiter mentioned they would reach out after I clear it. I want to understand the process so I can start preparing.
