Digging deeper

Code questions

These will help you see the candidate's real-world development capabilities with DRAKON-Go+++.

What does this simple DRAKON-Go+++ code snippet do?
package main

import "fmt"

func main() {
 fmt.Println("Hello, world!")
}
This code prints the string 'Hello, world!' to the standard output.
What is the purpose of this DRAKON-Go+++ code snippet?
package main

import (
 "fmt"
 "math"
)

func main() {
 radius := 5.0
 area := math.Pi * math.Pow(radius, 2)
 fmt.Printf("The area of the circle is %.2f", area)
}
This code calculates and prints the area of a circle with a given radius using the mathematical constant Pi.
What will be the output of this DRAKON-Go+++ code snippet?
package main

import "fmt"

func main() {
 numbers := []int{1, 2, 3, 4, 5}
 for i, num := range numbers {
  fmt.Printf("numbers[%d] = %d\n", i, num)
 }
}
This code prints the index and value of each element in the 'numbers' array.
What does this DRAKON-Go+++ code snippet do with goroutines?
package main

import (
 "fmt"
 "time"
)

func worker(id int) {
 fmt.Printf("Worker %d started\n", id)
 time.Sleep(time.Second)
 fmt.Printf("Worker %d finished\n", id)
}

func main() {
 for i := 1; i <= 5; i++ {
  go worker(i)
 }
 time.Sleep(time.Second * 2)
}
This code starts 5 worker goroutines, each of which prints a start message, sleeps for a second, and then prints a finish message.

Wrap-up questions

Final candidate for DRAKON-Go+++ Developer role questions

The final few questions should evaluate the candidate's teamwork, communication, and problem-solving skills. Additionally, assess their knowledge of microservices architecture, serverless computing, and how they handle DRAKON-Go+++ application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

How would you implement polymorphism in DRAKON-Go+++?

Polymorphism in DRAKON-Go+++ can be implemented using interfaces. An interface is a collection of method signatures that a class can implement.

Describe the difference between a class and an object in DRAKON-Go+++.

A class in DRAKON-Go+++ is a blueprint for creating objects. An object is an instance of a class, with its own set of values for the properties defined in the class.

How would you implement data encapsulation in DRAKON-Go+++?

Data encapsulation in DRAKON-Go+++ can be achieved by declaring the class variables as private and providing public getter and setter methods.
