Operating Systems (OS) Interview Questions

For an Operating Systems role, you'll need to demonstrate deep knowledge of OS fundamentals, system-level programming, and your ability to dive into the core of how computers work.

OS Fundamentals

These questions will test your understanding of the basic concepts behind operating systems.

• "Explain the difference between a process and a thread. When would you use one over the other?" This is a fundamental concept in OS. A process is an independent execution environment, while a thread is a lightweight unit of execution within a process. Use threads when you need concurrency within a single process to efficiently share resources, but use processes when you need isolation and robustness between different tasks to prevent issues in one task from crashing another.
• "What is virtual memory, and how does it work?" Virtual memory is a memory management technique that allows a process to access more memory than is physically available. It works by using disk space as an extension of RAM, swapping data between RAM and disk as needed. This allows programs to be larger than the available physical memory and also provides memory protection.
• "Describe the different types of scheduling algorithms used in operating systems." Scheduling algorithms determine the order in which processes are executed. Common algorithms include First-Come, First-Served (FCFS), Shortest Job First (SJF), Priority Scheduling, and Round Robin. Explain how each algorithm works, its advantages and disadvantages, and when it's most appropriate to use.

System-Level Programming

Expect questions that involve coding and low-level system interaction.

• "Have you ever written a device driver? If so, describe the challenges you faced." Device drivers are essential for allowing the OS to communicate with hardware. If you've written one, discuss the specific hardware you worked with, the driver's functionality, and any challenges you encountered (e.g., dealing with hardware interrupts, memory management, or synchronization issues). Even if you haven't written one, show a willingness to learn and explain the general process.
• "Explain how you would implement a mutex or semaphore in C." Mutexes and semaphores are synchronization primitives used to protect shared resources from concurrent access. Explain the basic concepts behind mutexes and semaphores and provide code snippets in C to demonstrate how you would implement them using system calls like pthread_mutex_lock, pthread_mutex_unlock, sem_wait, and sem_post. Be sure to mention the importance of avoiding deadlocks and race conditions.

Kernel Internals

These questions dive into the inner workings of the OS kernel.

• "What happens when you type a URL into your browser? Describe the steps the OS takes to resolve the domain name and establish a connection." This question tests your understanding of the networking stack and how the OS interacts with it. Walk through the steps, including DNS resolution, TCP/IP handshake, routing, and data transfer. Show that you understand the underlying protocols and how the OS manages network communication.
• "How does the OS handle interrupts?" Interrupts are signals that cause the OS to suspend its current activity and handle a specific event. Explain how the OS uses interrupt vectors to locate interrupt handlers, how it saves the current state of the processor, and how it returns to the interrupted process after handling the interrupt. Also, discuss the importance of interrupt priorities and how they are managed.

Enterprise Content Services (ECS) Interview Questions
