On completion, learners will earn a Certificate of Completion from Uplatz, validating expertise in Go programming, concurrency, and backend development. This boosts job prospects in cloud engineering, backend systems, and DevOps automation.

Go developers are in high demand in roles such as:

• Backend Developer (Go)

• Cloud Engineer (Go/Kubernetes)

• DevOps Engineer (Go tools)

• Microservices Developer

• Systems Programmer

Companies like Google, Uber, Dropbox, and Docker actively use Go in production, making it a highly employable skill.

1. What is Go and why was it created?
   Go is an open-source programming language created by Google for simplicity, concurrency, and performance, aimed at modern cloud-native development.

2. How does Go handle concurrency?
   Go uses goroutines (lightweight threads) and channels for communication, making concurrent programming simpler and safer.

3. What are Go interfaces?
   Interfaces define behavior without implementation. They allow polymorphism and are satisfied implicitly in Go.

4. What is the difference between slices and arrays in Go?
   Arrays have fixed length; slices are dynamic and built on top of arrays for flexibility.

5. What is the purpose of the defer statement in Go?
   defer schedules a function to run after the current function completes, often used for cleanup (e.g., closing files).

6. How does Go manage memory?
   Go uses garbage collection and stack-based memory allocation for efficiency.

7. What are goroutines?
   Goroutines are lightweight, concurrent execution units managed by Go’s runtime scheduler.

8. How do channels work in Go?
   Channels provide a way for goroutines to communicate safely by passing messages.

9. What is Go’s package system?
   Go organizes code into packages, enabling modularity and reusability. The go mod tool manages dependencies.

10. Where is Go commonly used?
    Go is widely used in cloud infrastructure (Kubernetes, Docker), web services, DevOps tools, distributed systems, and fintech apps.
