Sample answer
“In my internship at a software development company, I worked on a C project that involved data processing. I encountered a memory leak that caused the application to crash. I used tools like Valgrind to trace the source of the leak to an uninitialized pointer. After fixing the issue and running extensive tests, I improved the memory management. This experience taught me the importance of thorough testing and memory management in C programming.”
