Summary
I completed a 45‑minute C coderpad interview at Apple, answered three questions and solved them all, though I struggled to articulate my thought process.
How it went
Had my coderpad round at Apple (45 mins), 3 questions in total all in c.
- Check the Endianess of the machine.
- Debug a kernle module (It was a dead lock and few other optimization)
- A Medium binary search question.
Solved all of them, but messed up in explaing my thought process, assumeing this is too obvious to explain.
But, it was a good learning experience.
Questions asked (2)
- 01
Check Endianness of the Machine
Data Structures & Algorithms
Write a C program (or function) that determines whether the underlying system is little‑endian or big‑endian.
- 02
Debug Kernel Module Deadlock
Other
Given a kernel module that contains a deadlock, identify the cause of the deadlock and suggest possible optimizations.
