First answer excerpt
“I would optimize the frontend, lazy load some components, and make sure the API is faster so users do not wait as long.”
PrepBot feedback
Good direction, but the answer needs a diagnostic sequence, a tradeoff, and a measurable success condition.
Stronger answer direction
“I would first measure whether the delay is network, hydration, rendering, or expensive chart work. Then I would ship the lowest-risk improvement, such as paginated API data, skeleton states, or deferred charts, while watching load time and interaction delay.”
Why this is stronger
It starts with evidence, makes a defensible engineering choice, and finishes with how success will be verified.
