Title without skills
Many applicants hold the title without the skills. For years the product function rewarded storytelling, alignment, and strategy, and a whole group of PMs turned out to specialize in politics rather than technology or customers. Interviews heavy on driving alignment and stakeholder management are what the hiring team sees trending down.
The case study
Everyone hired at Whatnot in any role does a hands-on case study. Plenty of candidates present beautifully, then get a prompt and some data, write a PRD, and defend it out loud, and their thinking decays fast. What stands out instead is macro and micro thinking in the same person: a clear picture of the end state, plus impatience about how to validate it quickly.
What stands out
Specifics matter too. Many people at huge companies like Uber babysat things that already existed and polished the edges. The strong candidate was handed a problem and came up with something unique, or iterated through a complicated change and made decisions along the way.
Why do hands-on case studies reveal more?
In a 1998 meta-analysis, the psychologists Frank Schmidt and John Hunter reviewed decades of research on hiring methods. They found work sample tests, where candidates do a piece of the real job, predicted performance better than unstructured interviews, with validity of about 0.54 against about 0.38. A work sample gives the candidate no room to rely on a prepared story. Interviews built from open conversation reward fluency, which is a separate skill from doing the work.
Why do polished presenters seem more capable?
In 1920 the psychologist Edward Thorndike reported that military officers who rated soldiers high on one trait tended to rate them high on unrelated traits too. He called this the halo effect. A confident, well-structured presentation can create the same halo in an interviewer. This is one reason structured exercises with the same task for every candidate are often used to compare people.
