Programmers' salaries depend on technical level, and interview performance is key. To help candidates, we share two common interview questions from top Chinese internet companies.
Question 1 – Linux Partition Optimization
How to optimize Linux partitions?
Answer:
Place high‑traffic partitions (e.g., /boot, /home, /var, /tmp, /usr, swap) near the outer edge of the disk.
Create separate file systems for frequently accessed partitions.
If the disk has ample space, reserve some as spare space.
Use swap on fast disks to improve swap performance.
Other optimizations include choosing appropriate file systems.
Question 2 – Python String Query and Replace
How to query and replace a text string using Python?
Answer:
Use the sub() method from the re module.
