Answer
It can block other threads unnecessarily. Frame the concept in practical terms so you can explain it during interview discussion.
Using Thread.sleep() within a synchronized block can lead to thread contention and deadlocks, as it holds the lock while sleeping. This is inefficient and can cause performance hits. In a web server handling requests, this could severely degrade response times.
