GPM loops are about leverage through other PMs. Expect questions on portfolio trade-offs, developing people, and defending a strategy across a group rather than shipping a feature yourself.
Product loops are conversations with structure hidden inside them. The product-sense round wants a framework you actually use rather than one you have memorised, and the behavioral round wants metrics you can define precisely.
The most common failure is answering as a user rather than as an owner: describing what would be nice, with no reference to who it is for, what it costs, or how you would know it worked.
Each round is run by the interviewer built for it, with its own scoring axes — not one generic interviewer asked to change subject.

Six you can expect, in the register interviewers actually use. Answer them out loud before you read the next section — reading a question and answering one are different skills, and only the second is marked.
The gap between these two is most of your score, and it is easier to see than to be told.
“What do you do when a PM on your team makes a call you disagree with?”
Overriding it, or deferring entirely. The first destroys ownership; the second abdicates it. Both answer a simpler question than the one asked.
Distinguish reversible from irreversible. Let a reversible call stand and let them learn from it; intervene on the ones that cannot be undone, and be explicit with them about which this is and why. Leverage through other PMs is the whole assessment.
The post-mortem nobody sends you. These are specific to this loop rather than general interview advice.
For Group Product Manager, a general round runs with Maya — relentless star structure, metric definitions, and edge cases. It is the fastest way to find out which round you actually need to work on. The first session is free.
