Welcome to your interview.
The question is on your right: Design File Upload System. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
How would you design a file upload system if there is no cloud provider yet and files must be stored in the database, and how would you plan the migration once Scotiabank selects a cloud vendor later?
