No non-trivial project in the history of technology has ever gone exactly according to plan. The roadmap is a well-intentioned fiction. The sprint plan is a hypothesis. Reality is messy.
Unexpected roadblocks are not an exception; they are the rule. A key dependency will be delayed. The requirements will change mid-project. A critical team member will leave. You will uncover a massive, unforeseen technical challenge.
In these moments, it's easy to throw up your hands and declare the project a failure or the deadline impossible. But the most valuable professionals are the ones who see a roadblock not as a stop sign, but as a hurdle to be overcome. They possess a quality that is more valuable than any specific technical skill: grit.
Your answer to this question reveals your determination, your creativity in problem-solving, and your ability to perform under pressure.
