Question 27

What are the characteristics of good unit tests?

Question 28

What are table-driven tests and why are they commonly used in Go?

Question 29

What is the difference between:

  • Unit testing
  • Integration testing
  • Benchmark testing

Question 30

Why is code coverage alone not enough to measure software quality?

Section 8 – Benchmarking and Profiling

Question 31

What is benchmarking?

Question 32

Why should benchmarking be performed before optimization?

Question 33

What types of bottlenecks can profiling help identify?

Question 34

What is a goroutine leak?

Section 9 – CI/CD and Deployment

Question 35

What is CI/CD?

Question 36

How does CI/CD improve software reliability?

Question 37

What are the benefits of automated testing in CI pipelines?

Question 38

Why should formatting and linting checks be automated?

Section 10 – Security and Reliability

Question 39

Why should secrets never be committed to source control?

Question 40

What are some common backend security best practices?

Question 41

Why is dependency management important in Go applications?

Question 42

What risks are associated with outdated dependencies?

Section 11 – Engineering Mindset

Question 43

Why is readability considered important in Go?

Question 44

Explain the phrase:

“Clear is better than clever.”

Question 45

Why should engineers avoid overengineering solutions?

Question 46

What makes software maintainable over long periods of time?

Section 12 – Scenario Based Questions

Question 47

A backend service crashes frequently in production.

What steps would you take to investigate the issue?

Question 48

A service consumes excessive memory after running for several hours.

How would you troubleshoot the problem?

Question 49

An API is becoming slow under heavy load.

What areas would you investigate?

Question 50

A deployment succeeded, but users are receiving HTTP 500 errors.

How would you approach debugging the issue?

Reflection Questions

Question 51

What topics in this mentorship program did you find most challenging?

Question 52

Which Go concepts do you feel most confident about now?

Question 53

What areas do you want to explore next?

Examples:

  • Kubernetes operators
