Welcome to your interview.
The question is on your right: Algorithm Complexity for Scale. 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.
Explain the time complexity of searching and sorting algorithms in the context of large data sets.
