Problem Solving Frameworks
Interview Questions
Problem-solving frameworks are integral to interviews across various industries, from data analysis to software development. Candidates often struggle with these questions as they require not only technical acumen but also the ability to think logically and strategically under pressure. This challenge can stem from a lack of structured methodology or experience in applying the right framework to different types of problems.
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.
