I went through a full loop at Coca-Cola for a senior tech PM role. Three of my five rounds had significant behavioral components. Sharing the actual questions and my read on what they were really probing.
First: Coca-Cola explicitly structures their behavioral interviews around their stated values. The big ones they kept circling back to were something like "act like an owner", collaboration and inclusion, and growth mindset / continuous learning. They don't always name the value but you can feel the frame.
Questions I got (paraphrasing from memory): Tell me about a time you had to influence a cross-functional team where you had no direct authority. (Classic, but they pushed on the specifics of how you built buy-in, not just the outcome.) Describe a situation where you had to make a decision with incomplete data. What did you do and what would you do differently now? (They really wanted the retrospective angle. Not just "here's what I did.") Give me an example of a time you had to push back on leadership or a stakeholder. How did you handle it without damaging the relationship? (This one came up in two separate rounds in slightly different forms. Take it seriously.) Tell me about a time you worked on something that failed. What did you learn? (Standard. Don't over-explain the failure and under-explain the learning.) How have you approached building relationships with teams that are geographically or culturally different from your own? (Coca-Cola is a genuinely global company. This question felt very real, not performative.)
General observations: they were thorough on follow-ups. Giving a STAR answer wasn't enough if the story felt rehearsed. Two interviewers in particular kept asking "and then what happened" or "what would you do if the outcome had been different." It was collaborative rather than combative but you need depth on your stories.
One thing that felt different from pure tech company behavioral rounds: they cared about how you represent the company externally. A few questions touched on stakeholder communication and how you'd show up in meetings with bottler partners or retail customers. Context matters at Coke in ways it doesn't at a software startup.
Prepare at least 8-10 solid stories. You'll use more of them than you expect.
