Tell me about a project where you worked across multiple functions or departments within a client organization.

Reference answer

I led a customer experience transformation for a mid-market financial services firm. To do it right, I had to work across product, operations, marketing, and finance. Each function had different priorities and concerns. Product was worried we'd add complexity; operations was concerned about implementation costs; marketing wanted more aggressive customer acquisition changes; finance wanted to see ROI before committing resources. I didn't try to make everyone happy—that's impossible. Instead, I spent time upfront understanding each function's constraints and objectives, then built a roadmap that addressed the core pain points each function cared about. I created separate workstreams led by senior people from each function, which gave them ownership. I also established a weekly sync where we shared progress and resolved cross-functional tensions early rather than letting them build. When disagreements came up—and they did—I had data to back up decisions. The project succeeded because each function felt heard and saw how their priorities were reflected in the approach.
