Customer Obsession

Show that you start from the customer and work backwards: you seek out what users need, weigh it with data, and act on it even when it costs you something.

Overview

Customer questions test whether you make engineering decisions by starting from the people who use the product. Many companies say this in their values. Amazon lists Customer Obsession first among its Leadership Principles: 'Leaders start with the customer and work backwards. They work vigorously to earn and keep customer trust. Although leaders pay attention to competitors, they obsess over customers.' Google's list of things it knows to be true starts with 'Focus on the user and all else will follow.'

Saying 'I care about users' earns nothing. The interviewer wants evidence: you went looking for customer signal (support tickets, usage data, interviews), you changed a plan because of it, or you pushed back on something that would hurt users and offered a better path. The best stories show the gap between what customers asked for and what they needed.

Customer obsession is not doing whatever a customer asks. Strong answers show judgment: when to say yes, when to say no, and when to offer a better way.

The example stories on this page are fiction. They show the shape of a strong answer; use your own.

  • Source of insight — Went to tickets, data or users directly — Relied on the spec
  • Evidence — Measured the customer impact — 'Users were unhappy'
  • Cost — Advocacy cost time, scope or effort — Nothing was at stake
  • Judgment — Separated the need from the request — Built exactly what was asked
  • Outcome — A measured change for customers — 'They liked it'

What you will be able to do

  • Tell a story in which customer evidence changed an engineering decision.
  • Explain how you find what customers need, not just what they ask for.

  • Manage a change that hurts customers now to help them later.

Interview questions

  • Tell me about a time you advocated for the customer against business pressure.
  • How do you find out what customers actually need, not just what they ask for?
