Your question is Spotting a Cross-Sell Mid-Engagement. 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).
Tell me about a time you uncovered a new business need or cross-sell opportunity while you were already delivering an active client engagement. How did you validate the opportunity, align the right stakeholders, and pursue it without disrupting the work already in flight?
