Dodo++ is a programming language created by Matt Godbolt in the early 2000s. It is based on the C++ programming language, but with a simpler syntax and fewer features. Dodo++ was designed to be easier to learn and use than C++, and it has been used to create a variety of small programs. However, Dodo++ is not as widely used as other programming languages, such as C++ and Java.

First 20 minutes

General Dodo++ app knowledge and experience

The first 20 minutes of the interview should seek to understand the candidate's general background in Dodo++ application development, including their experience with various programming languages, databases, and their approach to designing scalable and maintainable systems.

How would you declare a variable in Dodo++?

In Dodo++, you declare a variable by specifying its type followed by the variable name. For example, 'int myVariable;' declares an integer variable named myVariable.

What are the basic data types in Dodo++?

The basic data types in Dodo++ are int, float, double, char, and bool.

Describe the difference between a class and an object in Dodo++.

A class is a blueprint for creating objects. An object is an instance of a class.

How would you define a function in Dodo++?

A function in Dodo++ is defined by specifying its return type, name, and parameters in parentheses. For example, 'int add(int a, int b) { return a + b; }' defines a function named add that takes two integers as parameters and returns their sum.

What are the control structures available in Dodo++?

The control structures available in Dodo++ are if, else, switch, for, while, and do-while.

Next 20 minutes

Specific Dodo++ development questions

The next 20 minutes of the interview should focus on the candidate's expertise with specific backend frameworks, their understanding of RESTful APIs, and their experience in handling data storage and retrieval efficiently.

Describe the difference between a stack and a heap in Dodo++.

A stack is used for static memory allocation and a heap for dynamic memory allocation. Variables created on the stack will automatically be deallocated when they go out of scope. On the other hand, variables created on the heap must be manually deallocated.

How would you handle exceptions in Dodo++?

Exceptions in Dodo++ are handled using the try, catch, and throw keywords. You enclose the code that might throw an exception in a try block and catch the exception in a catch block.

What are the different types of inheritance in Dodo++?

The different types of inheritance in Dodo++ are single, multiple, multilevel, hierarchical, and hybrid inheritance.

Describe the difference between overloading and overriding in Dodo++.

Overloading is when two or more functions in the same scope have the same name but different parameters. Overriding is when a derived class provides a different implementation of a method that is already provided by its base class.

How would you implement polymorphism in Dodo++?

Polymorphism in Dodo++ can be implemented using virtual functions. A virtual function is a function in a base class that can be overridden in a derived class.

Oops! Something went wrong while submitting the form.

At this point, a skilled Dodo++ engineer should demonstrate strong problem-solving abilities, proficiency in Dodo++ programming language, and knowledge of software development methodologies. Red flags include lack of hands-on experience, inability to articulate complex concepts, or unfamiliarity with standard coding practices.

Digging deeper

Code questions

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

What does the following Dodo++ code do?
let x = 10;
if (x > 5) {
  print('Hello, World!');
}
This code declares a variable 'x' and assigns it a value of 10. It then checks if 'x' is greater than 5. If 'x' is greater than 5, it prints 'Hello, World!' to the console.
What will be the output of the following Dodo++ code?
let x = [1, 2, 3, 4, 5];
let y = x.map(i => i * 2);
print(y);
This code declares an array 'x' with values from 1 to 5. It then uses the 'map' function to create a new array 'y' where each element is twice the corresponding element in 'x'. It then prints the array 'y'. The output will be [2, 4, 6, 8, 10].
What does the following Dodo++ code do?
let x = [1, 2, 3, 4, 5];
let y = x.filter(i => i % 2 == 0);
print(y);
This code declares an array 'x' with values from 1 to 5. It then uses the 'filter' function to create a new array 'y' where each element is an even number from 'x'. It then prints the array 'y'.
What does the following Dodo++ code do?
thread t1 = new thread(() => {
  for (int i = 0; i < 5; i++) {
    print(i);
  }
});
t1.start();
This code creates a new thread 't1' that runs a loop from 0 to 4 and prints each number. It then starts the thread 't1'.

Wrap-up questions

Final candidate for Dodo++ 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 Dodo++ application deployments. Inquire about their experience in handling system failures and their approach to debugging and troubleshooting.

What are the different types of casting in Dodo++?

The different types of casting in Dodo++ are static_cast, dynamic_cast, const_cast, and reinterpret_cast.

Describe the difference between a shallow copy and a deep copy in Dodo++.

A shallow copy copies all the member values from one object to another. A deep copy does the same but also duplicates the values that the pointers point to.

How would you manage memory in Dodo++?

Memory in Dodo++ is managed using the new and delete operators. The new operator is used to allocate memory on the heap, and the delete operator is used to deallocate memory from the heap.
