Stage 1 --------- Part 1 - asking about data structures and algorithms, questions about concurrency and parallelism both in general and in the context of Python. Part 2 - Object Oriented design question, something like design a airline booking system etc., Requirements were clear but what is expected wasn't in the sense that would they want to see some code or high level relationship diagrams (or both) - Stage 2 --------- Deeper understanding and troubleshooting of lower level network issues, disk protocols and being super handy with linux is highly expected.
