The LCP on the home page is around four seconds. How would you figure out the causes, and what would you do to bring it down?

How to approach it

The interviewer checks whether the candidate understands what LCP is and what that time is made of. It also matters whether they can diagnose the problem systematically: first the data source and the specific element, then the phase where time is lost, and only then targeted fixes, rather than "I'll do whatever Lighthouse says".
