You know how Google famously asked applicants brainteasers during the interview process? Like, how many basketballs can you fit into this office building? You and I always knew this was self-flattering, grandstanding nonsense that was predictive of nothing, and even Google management has finally come around. From Adam Bryant’s New York Times interview with Laszlo Bock, Google Senior Vice President of People Operations:
On the hiring side, we found that brainteasers are a complete waste of time. How many golf balls can you fit into an airplane? How many gas stations in Manhattan? A complete waste of time. They don’t predict anything. They serve primarily to make the interviewer feel smart.
Instead, what works well are structured behavioral interviews, where you have a consistent rubric for how you assess people, rather than having each interviewer just make stuff up.
Behavioral interviewing also works — where you’re not giving someone a hypothetical, but you’re starting with a question like, ‘Give me an example of a time when you solved an analytically difficult problem.’ The interesting thing about the behavioral interview is that when you ask somebody to speak to their own experience, and you drill into that, you get two kinds of information. One is you get to see how they actually interacted in a real-world situation, and the valuable ‘meta’ information you get about the candidate is a sense of what they consider to be difficult.
On the leadership side, we’ve found that leadership is a more ambiguous and amorphous set of characteristics than the work we did on the attributes of good management, which are more of a checklist and actionable.
We found that, for leaders, it’s important that people know you are consistent and fair in how you think about making decisions and that there’s an element of predictability. If a leader is consistent, people on their teams experience tremendous freedom, because then they know that within certain parameters, they can do whatever they want. If your manager is all over the place, you’re never going to know what you can do, and you’re going to experience it as very restrictive.”
