C# Concurrency for Senior Engineering Interviews Course Syllabus

A hands-on, FAANG-grade course designed to master C# concurrency for senior engineering interviews. This 15-hour program combines theory and practice through interactive coding challenges, covering low-level threading to advanced async patterns and real-world interview problems. Built by ex-MAANG engineers, it delivers targeted, interview-focused learning with immediate feedback and performance analysis.

Module 1: Basics

Estimated time: 3 hours 45 minutes

• Concurrency fundamentals—process vs. thread
• Race conditions, deadlocks, and liveness issues
• Mutex vs. monitor semantics
• Amdahl’s Law and concurrency limits

Module 2: API Overview

Estimated time: 5 hours 15 minutes

• .NET threading APIs: ThreadLocal and ThreadPool
• Tasks and WaitHandles for synchronization
• SpinLock, Barrier, and CountdownEvent usage
• volatile keyword and interlocked operations

Module 3: Asynchronous Programming

Estimated time: 1 hour 45 minutes

• Async/await mechanics in C#
• Differentiating I/O-bound vs. CPU-bound tasks
• Common caveats in asynchronous code

Module 4: Interview Practice Problems

Estimated time: 4 hours

• Implementing a thread-safe BlockingQueue
• Token Bucket rate limiting algorithm
• Deferred callbacks and readers-writer locks
• Dining Philosophers and Uber Ride problem
• Multithreaded merge sort implementation

Module 5: The End

Estimated time: 15 minutes

• Course wrap-up and key takeaways
• Best practices for interview communication
• Teamwork and feedback in system design discussions

Prerequisites

• Familiarity with C# syntax and object-oriented programming
• Basic understanding of .NET runtime and memory management
• Experience with debugging and writing unit tests in C#

What You'll Be Able to Do After

• Explain advanced C# concurrency primitives clearly in interviews
• Distinguish concurrency vs. parallelism and preemptive vs. cooperative multitasking
• Solve classic synchronization problems like Reader–Writer and Producer–Consumer in C#
• Apply lock-free patterns and atomic operations to real-world scenarios
• Design efficient async workflows and communicate trade-offs effectively during system design rounds
