Yup, but my earlier comment was a bit flippant, so here’s a more in-depth response.
It was an answer to the OP’s question about why Gmail search feels broken, and a nod to the previous comment pointing out Google’s core business is selling ads. In that context, Gmail isn’t optimized for superior search. It’s part of a data funnel that enables keyword targeting, ad placement, and behavioral profiling.
For me, there’s a deeper product lesson here, but also a signal about how someone thinks. Whether a candidate answers “ads” or “search” or “email” isn’t what really matters. It’s the why behind the answer that matters most.
At the end of the day, business models directly shape product decisions. That tension is something every product manager has to navigate because they sit between the business and technical sides of a company. Being able to see and articulate that tradeoff, especially when user needs diverge from monetization incentives, is key to both building effectively and being a successful product manager.
More often the business model, like subscriptions, is more tightly connected to the product. User has X problem that product Y solves and the company receives Z dollars in exchange for access. However, there are many examples where the pricing or monetization strategy is not so clearly connected to the feature set, of which google search is a great example.
For the record, I don't ask this question to junior PMs.
