This easy-level Python/Coding question appears frequently in data engineering interviews at companies like JP Morgan. While less common, it tests deeper understanding that distinguishes strong candidates.
Start by clearly defining the core concept being asked about. Interviewers want to see that you understand the fundamentals before diving into implementation details. Structure your answer with a definition, then explain the practical application with a concise example.
Default Thread.run(): Calls the Runnable's run() if constructed with Runnable. If you extend Thread and don't override run(), and pass no Runnable, run() does nothing—thread starts and exits immediately.
Why It Matters: Silent no-op—hard to debug. Always override run() when extending Thread, or pass Runnable to constructor (preferred—avoids inheritance).
