Introduction
This question assesses your problem-solving skills and understanding of performance optimization within the LAMP stack, which is critical for a junior developer.
How to answer
What not to say
Example answer
“When faced with a slow PHP application, my first step would be to check the server logs for any errors or bottlenecks. I would use tools like Xdebug to profile the application and identify slow functions. For instance, I once found that a poorly optimized query was slowing down the app. I rewrote it to use indexing and reduced the execution time by 75%. After implementing the fix, I monitored performance to ensure stability.”
