How do you debug slowness and bugs?
Company: Bobyard
Role: Software Engineer
Category: Software Engineering Fundamentals
Difficulty: medium
Interview Round: Technical Screen
The interviewer asked two practical engineering questions:
1. A web application's frontend is loading very slowly. Describe how you would diagnose the issue end to end, identify the exact bottleneck such as a specific component, asset, API, or DOM element, and then improve performance.
2. A production bug has been discovered. Explain how you would assess severity, mitigate impact, investigate root cause, communicate with stakeholders, deploy a fix safely, and prevent recurrence.
Overview: This question evaluates troubleshooting and incident-response competencies, including performance debugging, root-cause analysis, severity assessment, mitigation and impact reduction, stakeholder communication, and safe deployment practices for web applications.
