Basically, they came to my university and we had a phone interview. After that, they selected a group to fly up to redmond for the weekend and we had a full day of interviews. Each interview is with a different team that you can work with and all operate roughly independently (i.e. if you bomb one, you can still get in with a different team). After that, you wait for each team to decide whether they want you (they typically choose their top few candidates and then get the first one that isnt taken by another group).

It started with a 90-minute online assessment, followed by a technical phone screen with one engineer. The OA covered two medium-to-hard algorithm problems. For coding practice, I mainly rely on "LeetCode" to cover different topics. For company-specific interview preparation, I use "Hack2Hire", "LeetCode Discuss", and "1Point3Acres" to find any recent original questions. All of them are helpful platforms. The phone screen included one coding problem and some discussion around edge cases and time complexity.
