Why Problem Solving Frameworks Matters

Interviewers use problem-solving questions to evaluate a candidate’s ability to navigate complex scenarios efficiently and effectively. In roles where decision-making under uncertainty is common, like data science or project management, frameworks offer a guided approach to breaking down and resolving issues. Interviewers assess whether a candidate can apply structured approaches like MECE or the 5 Whys to diagnose and resolve multifaceted problems, distinguishing strong, methodical thinkers from those who might panic or become overwhelmed.
