  • [ ] Pass an int and Mutex to each and count when they return.
  • [ ] Loop over a select statement.
  • [ ] Sleep for a safe amount of time.
  • [x] sync.WaitGroup

Explanation: this is exactly what sync.WaitGroup is designed for – Use sync.WaitGroup in Golang

Q13. What is a side effect of using time.After in a select statement?

  • [ ] It blocks the other channels.
  • [x] It is meant to be used in select statements without side effects.
  • [ ] It blocks the select statement until the time has passed.
  • [ ] The goroutine does not end until the time passes.

  • [ ] Saveable
  • [ ] SaveInterface
  • [ ] ISave
  • [x] Saver

Effective Go, Interface names

Q21. A switch statement _ its own lexical block. Each case statement _ an additional lexical block.

  • [ ] does not create; creates
  • [ ] does not create; does not create
  • [x] creates; creates
  • [ ] creates; does not create

Go Language Core technology (Volume one) 1.5-scope

Relevant excerpt from the article:

The second if statement is nested inside the first, so a variable declared in the first if statement is visible to the second if statement. There are similar rules in switch: Each case has its own lexical block in addition to the conditional lexical block.

Q22. What is the default case sensitivity of the JSON Unmarshal function?

  • [x] The default behavior is case insensitive, but it can be overridden.
  • [ ] Fields are matched case sensitive.
  • [ ] Fields are matched case insensitive.
  • [ ] The default behavior is case sensitive, but it can be overridden.


Relevant excerpt from the article:

To unmarshal JSON into a struct, Unmarshal matches incoming object keys to the keys used by Marshal (either the struct field name or its tag), preferring an exact match but also accepting a case-insensitive match. By default, object keys which don’t have a corresponding struct field are ignored (see Decoder.DisallowUnknownFields for an alternative).

Q23. What is the difference between the time package’s Time.Sub() and Time.Add() methods?

  • [ ] Time.Add() is for performing addition while Time.Sub() is for nesting timestamps.
  • [ ] Time.Add() always returns a later time while time.Sub always returns an earlier time.
  • [ ] They are opposites. Time.Add(x) is the equivalent of Time.Sub(-x).
  • [x] Time.Add() accepts a Duration parameter and returns a Time while Time.Sub() accepts a Time parameter and returns a Duration.



Q24. What is the risk of using multiple field tags in a single struct?

  • [ ] Every field must have all tags to compile.
  • [x] It tightly couples different layers of your application.
  • [ ] Any tags after the first are ignored.
  • [ ] Missing tags panic at runtime.

Example Code / b29r0fUD1cp

Q25. Where is the built-in recover method useful?

  • [ ] in the main function
  • [ ] immediately after a line that might panic
  • [x] inside a deferred function
  • [ ] at the beginning of a function that might panic

Example of Recover Function in Go (Golang)

Relevant excerpt from the article:

Recover is useful only when called inside deferred functions. Executing a call to recover inside a deferred function stops the panicking sequence by restoring normal execution and retrieves the error message passed to the panic function call. If recover is called outside the deferred function, it will not stop a panicking sequence.

Q26. Which choice does not send output to standard error?

  • [x] println(message)
  • [ ] log.New(os.Stderr, “”, 0).Println(message)
  • [ ] fmt.Errorf(“%s\n”, message)
  • [ ] fmt.Fprintln(os.Stderr, message)

Q27. How can you tell Go to import a package from a different location?

  • [ ] Use a proxy.
  • [ ] Change the import path.
  • [x] Use a replace directive in go.mod.
  • [ ] Use a replace directory.

Q28. If your current working directory is the top level of your project, which command will run all its test packages?

  • [ ] go test all
  • [ ] go run –all
  • [ ] go test .
  • [x] go test ./…

Example of testing in Go (Golang)

Example of cmd in Go (Golang)

Relevant excerpt from the article:

Relative patterns are also allowed, like “go test ./…” to test all subdirectories.

Q29. Which encodings can you put in a string?

  • [ ] any, it accepts arbitary bytes
  • [ ] any Unicode format
  • [ ] UTF-8 or ASCII
  • [x] UTF-8

Example of encoding in Go (Golang)

Relevant excerpt from the article:

Package encoding defines an interface for character encodings, such as Shift JIS and Windows 1252, that can convert to and from UTF-8.

Q30. How is the behavior of t.Fatal different inside a t.Run?

  • [ ] There is no difference.
  • [ ] t.Fatal does not crash the test harness, preserving output messages.
  • [x] t.Fatal stops execution of the subtest and continues with other test cases.
  • [ ] t.Fatal stops all tests and contains extra information about the failed subtest.


Fatal is equivalent to Log followed by FailNow.
Log formats its arguments using default formatting, analogous to Println, and records the text in the error log.
FailNow marks the function as having failed and stops its execution by calling runtime.Goexit (which then runs all deferred calls in the current goroutine). Execution will continue at the next test or benchmark. FailNow must be called from the goroutine running the test or benchmark function, not from other goroutines created during the test. Calling FailNow does not stop those other goroutines.
Run runs f as a subtest of t called name. It runs f in a separate goroutine and blocks until f returns or calls t.Parallel to become a parallel test. Run reports whether f succeeded (or at least did not fail before calling t.Parallel).
Run may be called simultaneously from multiple goroutines, but all such calls must return before the outer test function for t returns.

Q31. What does log.Fatal do?

  • [ ] It raises a panic.
  • [ ] It prints the log and then raises a panic.
  • [x] It prints the log and then safely exits the program.
  • [ ] It exits the program.

Example of func Fatal in Go (Golang)

Relevant excerpt from the article:

Fatal is equivalent to Print() followed by a call to os.Exit(1).

Q32. Which is a valid Go time format literal?

  • [x] “2006-01-02”
  • [ ] “YYYY-mm-dd”
  • [ ] “y-mo-d”
  • [ ] “year-month-day”

Example of func Time in Go (Golang)

Relevant excerpt from the article:

Most programs can use one of the defined constants as the layout passed to Format or Parse. The rest of this comment can be ignored unless you are creating a custom layout string.

Q33. How should you log an error (err)

  • [ ] log.Error(err)
  • [x] log.Printf("error: %v", err)
  • [ ] log.Printf(log.ERROR, err)
  • [ ] log.Print("error: %v", err)

Explanation: There is defined neither log.ERROR, nor log.Error() in log package; log.Print() arguments are handled in the manner of fmt.Print(); log.Printf() arguments are handled in the manner of fmt.Printf().

Q34. Which file names will the go test command recognize as test files?

  • [ ] any that starts with test
  • [ ] any files that include the word test
  • [ ] only files in the root directory that end in _test.go
  • [x] any that ends in _test.go

Q35. What will be the output of this code?

ch := make(chan int)
ch <- 7
val := <-ch
  • [ ] 0
  • [x] It will deadlock
  • [ ] It will not compile
  • [ ] 2.718

Q36. What will be the output of this program?

ch := make(chan int)
val := <-ch
  • [ ] It will deadlock
  • [ ] It will panic
  • [x] 0
  • [ ] NaN

Q37. What will be printed in this code?

var stocks map[string]float64 // stock -> price
price := stocks["MSFT"]
fmt.Printf("%f\n", price)
  • [ ] 0
  • [x] 0.000000
  • [ ] The code will panic
  • [ ] NaN

Q38. What is the common way to have several executables in your project?

  • [x] Have a cmd directory and a directory per executable inside it.
  • [ ] Comment out main.
  • [ ] Use build tags.
  • [ ] Have a pkg directory and a directory per executable inside it.
  1. stackoverflow
  2. medium
  3. medium

Q39. How can you compile main.go to an executable that will run on OSX arm64 ?

  • [ ] Set GOOS to arm64 and GOARCH to darwin.
  • [ ] Set GOOS to osx and GOARCH to arm64.
  • [ ] Set GOOS to arm64 and GOARCH to osx.
  • [x] Set GOOS to darwin and GOARCH to arm64.


Q40. What is the correct syntax to start a goroutine that will print Hello Gopher!?

  • [ ] go(fmt.Println("Hello Gopher!"))
  • [ ] go func() { fmt.Println("Hello Gopher!") }
  • [x] go fmt.Println("Hello Gopher!")
  • [ ] Go fmt.Println("Hello Gopher!")

Example of start a goroutine

Q41. If you iterate over a map in a for range loop, in which order will the key:value pairs be accessed?

  • [x] in pseudo-random order that cannot be predicted
  • [ ] in reverse order of how they were added, last in first out
  • [ ] sorted by key in ascending order
  • [ ] in the order they were added, first in first out


Q42. What is an idiomatic way to customize the representation of a custom struct in a formatted string?

  • [ ] There is no customizing the string representation of a type.
  • [ ] Build it in pieces each time by calling individual fields.
  • [x] Implement a method String() string
  • [ ] Create a wrapper function that accepts your type and outputs a string.
