Scenario Questions
- A Frontend change causes slower responses after traffic increases. I would isolate the hot path, apply the smallest reversible fix, and verify the result with latency, error rate, and rollback readiness.

Common Mistakes
- performance is good because it is faster. I would compare the workload, failure mode, and maintenance cost before using performance, then verify the result with production metrics.
- accessibility is good because it is faster. I would compare the workload, failure mode, and maintenance cost before using accessibility, then verify the result with production metrics.
- caching is good because it is faster. I would compare the workload, failure mode, and maintenance cost before using caching, then verify the result with production metrics.
- cors is good because it is faster. I would compare the workload, failure mode, and maintenance cost before using cors, then verify the result with production metrics.
- state-management is good because it is faster. I would compare the workload, failure mode, and maintenance cost before using state-management, then verify the result with production metrics.

Compact Interview Questions
How do you improve frontend performance?
Measure first, reduce JavaScript, optimize images, split code, cache assets, and avoid unnecessary rendering.
What is accessibility in frontend development?
Accessibility makes interfaces usable with keyboards, screen readers, sufficient contrast, semantic HTML, and clear focus states.
How does browser caching work?
Browsers cache responses based on headers such as Cache-Control, ETag, Expires, and validation rules.
