Hoping this is late enough not to be useful with your interview but soon enough to help you learn something
Why does this bring to mind the vision of an interviewee tapping away at an iPad during the interview, posting a question to SSC, in the hopes that it will be answered by the time the interviewer blinks twice?
My thought question: Have you ever been told that your query runs too fast?
My advice:
INDEXing a poor-performing query is like putting sugar on cat food. Yeah, it probably tastes better but are you sure you want to eat it?
The path of least resistance can be a slippery slope. Take care that fixing your fixes of fixes doesn't snowball and end up costing you more than fixing the root cause would have in the first place.
