First 20 minutes

General KRYPTON app knowledge and experience

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

What are the basic principles of KRYPTON?
The basic principles of KRYPTON include abstraction, encapsulation, inheritance, and polymorphism. It also emphasizes on code reusability and modularity.
How would you initialize a variable in KRYPTON?
In KRYPTON, a variable can be initialized using the 'var' keyword followed by the variable name and the assignment operator. For example, 'var x = 10;' initializes a variable x with the value 10.
What is the use of the 'this' keyword in KRYPTON?
In KRYPTON, the 'this' keyword is used to refer to the current instance of the class. It can be used to access the class members such as fields and methods.
Describe the difference between '==' and '===' operators in KRYPTON.
In KRYPTON, '==' is an equality operator that compares two values for equality after performing type coercion if necessary. On the other hand, '===' is a strict equality operator that compares two values for equality without performing type coercion.
How would you create a function in KRYPTON?
In KRYPTON, a function can be created using the 'function' keyword followed by the function name and parentheses. The function body is enclosed within curly braces. For example, 'function myFunction() { // function body }'.

Next 20 minutes

Specific KRYPTON 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.

What are the different types of loops in KRYPTON?
KRYPTON supports several types of loops including 'for', 'while', and 'do-while'. Each of these loops can be used depending on the specific requirements of the code.
How would you handle exceptions in KRYPTON?
In KRYPTON, exceptions can be handled using the 'try-catch' block. The 'try' block contains the code that might throw an exception, and the 'catch' block contains the code to handle the exception.
Describe the difference between a class and an object in KRYPTON.
In KRYPTON, a class is a blueprint or template that defines the characteristics and behaviors of objects, while an object is an instance of a class.
What are closures in KRYPTON and how would you use them?
In KRYPTON, closures are functions that have access to the parent scope, even after the parent function has closed. They are used to implement data privacy and function factories.
How would you implement inheritance in KRYPTON?
In KRYPTON, inheritance can be implemented using the 'extends' keyword. The child class extends the parent class, inheriting all its properties and methods.

The ideal back-end app developer

What you’re looking to see on the KRYPTON engineer at this point.

At this point, a skilled KRYPTON engineer should demonstrate strong problem-solving abilities, proficiency in KRYPTON 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 KRYPTON.

What does the following KRYPTON code snippet do?
var x = 10;
var y = 20;
var z = x + y;
This code declares two variables x and y, assigns them the values 10 and 20 respectively, adds them together and assigns the result to a new variable z. It then prints the value of z, which will be 30.
What will be the output of the following KRYPTON code?
var x = 'Hello, ';
var y = 'World!';
var z = x + y;
This code concatenates two strings 'Hello, ' and 'World!' and assigns the result to a new variable z. It then prints the value of z, which will be 'Hello, World!'.
What does the following KRYPTON code snippet do?
var arr = [1, 2, 3, 4, 5];
var sum = 0;
for (var i = 0; i < arr.length; i++) {
  sum += arr[i];
This code declares an array of five numbers and a variable sum initialized to 0. It then iterates over the array, adding each element to sum. Finally, it prints the value of sum, which will be the sum of all elements in the array.
What does the following KRYPTON code snippet do?
var thread = new Thread(() => {
  for (var i = 0; i < 10; i++) {
This code creates a new thread that runs a loop printing numbers from 0 to 9. The thread is then started, causing the loop to execute in a separate thread of execution.

Wrap-up questions

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

What is the event loop in KRYPTON?
The event loop in KRYPTON is a mechanism that handles and processes external events and converts them into callback invocations. It's responsible for executing the code, collecting and processing events, and executing queued sub-tasks.
How would you create a promise in KRYPTON?
In KRYPTON, a promise can be created using the 'Promise' constructor which takes an executor function as an argument. The executor function takes two parameters: resolve and reject which are used to indicate the completion or failure of the promise.
Describe the difference between synchronous and asynchronous programming in KRYPTON.
In synchronous programming, operations are executed sequentially and an operation blocks until its completion. In asynchronous programming, operations can execute concurrently and do not block the execution of other operations.
