Your question is Variance Analysis Approach. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
Explain the logic behind your approach to variance analysis when actuals deviate from your initial budget.
In your answer, focus on how you would separate volume, price, mix, and timing effects, and how you would decide whether a variance is one-time or structural. Keep the response practical and concise, as if speaking to a CFO in an interview.
