I recently completed my Amazon SDE 1 virtual onsite interviews and wanted to share my experience to give back to the community! :)
Round 1: 60 mins (with an SDM)
Round 2: 60 mins (with an SDM)
This round was entirely behavioral. Be sure to thoroughly review and understand Amazon's Leadership Principles (LPs). Prepare 5-6 stories that align with these principles, as there will be multiple follow-up questions on your responses.
Round 3: 60 mins (with an SDE 2)
This round was a mix of technical and behavioral questions. I was asked to design a package system where each package can have one or more dependencies. I needed to define what a package would look like and provide a coded solution. I highly recommend studying Object-Oriented Design (OOD) patterns and practicing at least 5-6 OOD design problems to fully grasp how such systems work.
Good luck to everyone!
UPDATE: I got the offer :)
