Last year, Google said it was moving away from the crazy brainteasers it used to
ask
people in job interviews in favor of structured, behavioral queries
like, "Give me an example of a time when you solved an analytically
difficult problem."
At the time, the company's SVP of people
operations, Laszlo Bock, said this line of questioning provided more
information about a candidate's abilities than bizarre hypotheticals
like, "How much should you charge to wash all the
windows in Seattle?"
But a new video the company published recently reveals another reason
Google has shifted to a standardized set of questions: It helps prevent
hiring managers' implicit biases about gender and race from influencing their decisions.
The video shows a presentation about unconscious biases that Google
director of people analytics Dr Brian Welle gave to a group of company
founders, which Google has invested in through its Google Ventures fund.
The presentation is part of Google's big push to improve diversity at
the tech giant after it released data in May that showed only 30% of
Google employees are women and only 5% are black or Hispanic.
At about 20 minutes and 50 seconds into the video, Welle explains how a
2005 study in Psychological Science shows why having a set criteria and
standardized questions prevents people from making biased hiring
decisions. In that study, participants were shown resumes with male and
female names, and asked to choose which resume would make someone best
suited for the traditionally male role of police chief.

Welle says the participants preferred male candidates, and when asked
why they did not choose a female, they responded that the female
candidate in question was lacking either street smarts or school smarts.
But when the participants were asked to first identify whether they
preferred school smarts or street smarts before looking at resumes,
Welle says the gender bias that had pervaded the first study was
eliminated.
The lesson, he says, is that it's important to articulate the exact
things Google is looking for in every position it fills. And, instead of
asking random brainteasers, the company now asks questions specifically
related to the qualities it has said it is looking for.
"Every
question in our interview protocol is tied to a competence that we know
you need to have to excel, and then we make sure that if I interviewed
five people for that one role, all five people have answered the exact
same questions," Welle says.
