Wyvern is an innovative, statically-typed object-oriented programming language that primarily focuses on enhancing the safety and productivity of software developers. It was created at Carnegie Mellon University with a vision to provide a robust platform for building highly secure systems. The inception of Wyvern dates back to 2013 when its creators sought to develop a programming language that could mitigate common security vulnerabilities often found in other popular languages. By integrating unique features such as type-specific methods and capability-based access control, Wyvern offers enhanced security measures designed specifically for high-assurance systems. One defining characteristic of Wyvern is its ability to support architectural design at the code level by compartmentalizing different parts into modules. This feature enhances modularity and allows developers greater flexibility in organizing their codebase without compromising on safety or reliability. Additionally, ano

First 20 minutes

General Wyvern. app knowledge and experience

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

How would you describe Wyvern?

Wyvern is a statically typed, functional, object-oriented programming language that aims to provide secure and efficient code development. It is designed to be simple and easy to read, while also providing powerful abstraction mechanisms.

What are the key features of Wyvern?

Key features of Wyvern include static typing, object-oriented programming, functional programming, and a focus on security. It also supports type-specific languages, which allow different types of data to be represented in the most natural way.

Describe the difference between static and dynamic typing in Wyvern.

In Wyvern, static typing means that the type of a variable is known at compile time, which can help catch errors early. Dynamic typing, on the other hand, means that the type is checked at runtime, which can provide more flexibility but may also lead to runtime errors.

How would you handle errors in Wyvern?

In Wyvern, errors can be handled using exception handling mechanisms. This involves using 'try' and 'catch' blocks to catch and handle exceptions. Additionally, the type system can help prevent many common types of errors.

What are type-specific languages in Wyvern and how do they work?

Type-specific languages in Wyvern are a way to represent different types of data in the most natural way. This means that each type can have its own syntax and semantics, which can make the code more readable and easier to understand.

Next 20 minutes

Specific Wyvern. 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.

How would you implement a function in Wyvern?

In Wyvern, functions are defined using the 'def' keyword, followed by the function name, parameters, and body. The return type of the function can also be specified.

Describe the difference between functional and object-oriented programming in Wyvern.

Functional programming in Wyvern involves writing pure functions that avoid changing state and mutable data. Object-oriented programming, on the other hand, involves organizing code into objects that contain both data and methods.

What are the benefits of using Wyvern over other programming languages?

Benefits of using Wyvern include its focus on security, its support for both functional and object-oriented programming, and its type-specific languages. Additionally, its simplicity and readability can make it easier to write and maintain code.

How would you ensure code quality in Wyvern?

Code quality in Wyvern can be ensured through good coding practices, such as following the DRY (Don't Repeat Yourself) principle, writing clear and concise code, and using the type system effectively. Additionally, testing and code reviews can help catch and fix errors.

What are the security features of Wyvern?

Wyvern has a strong focus on security. Its type system can help prevent many common types of errors, and it also supports capabilities-based security, which can provide fine-grained control over what code can do.

Oops! Something went wrong while submitting the form.

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

What does the following code do?
{ 'name': 'John', 'age': 30, 'city': 'New York' }
This code defines a JSON object with three properties: name, age, and city. The values of these properties are 'John', 30, and 'New York' respectively.
What will be the output of the following code?
{ 'employees': ['John', 'Anna', 'Peter'], 'number': 3 }
This code defines a JSON object with two properties: employees and number. The employees property is an array containing three strings: 'John', 'Anna', and 'Peter'. The number property has a value of 3.
What does the following code do?
{ 'employees': [{ 'firstName':'John', 'lastName':'Doe' }, { 'firstName':'Anna', 'lastName':'Smith' }, { 'firstName':'Peter', 'lastName':'Jones' }] }
This code defines a JSON object with one property: employees. The employees property is an array containing three objects, each with properties firstName and lastName.
What will be the output of the following code?
{ 'person': { 'name': 'John', 'age': 30, 'city': 'New York' }, 'isEmployee': true }
This code defines a JSON object with two properties: person and isEmployee. The person property is an object with three properties: name, age, and city. The isEmployee property is a boolean with a value of true.

Wrap-up questions

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

How would you optimize performance in Wyvern?

Performance in Wyvern can be optimized through techniques such as efficient algorithm design, effective use of data structures, and avoiding unnecessary computation. Additionally, the Wyvern compiler can also perform optimizations.

Describe the difference between capabilities-based security and role-based security in Wyvern.

Capabilities-based security in Wyvern provides fine-grained control over what code can do by associating permissions with objects. Role-based security, on the other hand, assigns permissions to roles, which can then be assigned to users.

What are the limitations of Wyvern?

Limitations of Wyvern include its relative newness, which means that it may not have as many libraries or resources available as more established languages. Additionally, while its simplicity can be a benefit, it may also limit its flexibility in some cases.
