I went through the Salesforce loop for a senior PMM role last year and the behavioral rounds were more rigorous than I expected for a non-engineering role. Wanted to document this for anyone coming from marketing, sales, or ops.
Salesforce's stated core values are trust, customer success, innovation, equality, and sustainability. In practice, the behavioral questions cluster around trust and customer success most heavily. Equality came up in one question but it felt more pro forma.
Questions I actually got asked: "Tell me about a time you had to make a decision with incomplete data and a tight deadline." "Describe a project where you had to build alignment across teams that had competing priorities." "Tell me about a time you pushed back on something a senior stakeholder wanted to do." "Give me an example of when you put the customer's needs ahead of your own team's preferences."
The push-back question caught a few people in my cohort off guard. They want to see that you have a spine, not just that you're agreeable. If you only tell stories where you deferred to leadership, they'll probe harder. Have a story ready where you respectfully disagreed and it led somewhere.
Format: they want STAR (situation, task, action, result). They will ask follow-up questions if your result is vague. Practice quantifying outcomes. "Increased pipeline by X%" beats "the campaign performed well."
One interviewer specifically said she was looking for evidence of "operating with integrity even when it's inconvenient." So think about stories that touch on doing the right thing when there was a cost.
For PMM specifically they also asked a product knowledge question: describe how you'd position one Salesforce product to a mid-market customer who's evaluating a competitor. So know the product portfolio at a basic level before going in.
