Amazon Robotics Software Engineer Intern interview questions

I applied for it on a university job portal. The recruiter reached out and sent me OA right after. There were 2 DSA questions in the OA, all test cases passed. I had one interview after that, where they asked me a design question. Something like you need to design a storage organizer, given the box sizes S, M, and L. Get the object size specs from the user, choose the appropriate box for storage, and provide a unique key to the user to access the storage later.
