Golang Pro: Elevate Your Development Skills – Series 1

## 🧠 Agenda:

### 1. Coding Challenge: Implementing a Concurrent Safe Cache (25 mins)

• Objective: Design and implement a thread-safe in-memory cache in Go that supports concurrent read and write operations.
• Key Concepts: Goroutines, mutexes, channels, and synchronization.
• Discussion Points:
• Ensuring data consistency in concurrent environments.
• Performance trade-offs between different synchronization techniques.

***

### 2. Face-to-Face Interview Simulation: Debugging a Goroutine Leak (25 mins)

• Scenario: You're presented with a Go application that exhibits increased memory usage over time.
• Tasks:
• Identify and resolve the goroutine leak causing the memory issue.
• Discuss best practices to prevent such leaks.
• Key Concepts: Goroutine lifecycle management, context cancellation, and profiling tools

***

### 3. System Design Session: Designing a URL Shortener Service in Go (35 mins)

• Objective: Architect a scalable and efficient URL shortening service similar to Bitly.
• Discussion Points:
• Database schema design and storage strategies.
• API design and rate limiting.
• Handling high availability and fault tolerance.

***

### 4. Real-World Product Issue: Handling Panic and Recover in Production (25 mins)

• Scenario: A production Go application crashes due to an unhandled panic.
• Tasks:
• Implement panic recovery mechanisms to prevent application crashes.
• Discuss logging and alerting strategies for such incidents.
• Key Concepts: Error handling, defer-panic-recover pattern, and observability

***

### 5. Q&A and Interactive Discussion (30 mins)

• Open floor for attendees to ask questions, share experiences, and discuss challenges faced during interviews or in real-world Go projects.
