This is the framework Talhive uses to move from a large candidate pool to a shortlist of three people who are genuinely likely to succeed in the role, not just the role as described on the interview loop.
Why Most PM Funnels Fail
The standard PM funnel rewards preparation and articulation, two skills PMs practice deliberately. A candidate who has been coached on product sense, strategy, and stakeholder frameworks will perform well in every standard stage. The actual signal is almost always elsewhere: in how they describe decisions they got wrong, in whether engineers who worked under them would work under them again, in the quality of their thinking when the case problem is made harder than they prepared for.
Stage 1: Async Pre-Screen
For high volume, send a short written pre-screen before the first call. Ask for a product decision they made, what they considered, what they chose, and what happened. This single question filters dramatically: strong PMs write with specificity, acknowledge tradeoffs, and do not reach for frameworks. Weak ones describe process. Read the answer, do not just collect it.
