Welcome to your interview.
The question is on your right: De-Duplicate Financial Feed Records. 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.
Write a Python script to identify and remove duplicate records from an incoming financial data feed where duplicates are defined by a combination of timestamp, ticker, and transaction size within a microsecond threshold.
